How to compare prices online and find tools to help
Merchant sale dates, pricing, products, services, and policies are subject to change.
Finding multiple prices for the same product can take just a few clicks. Figuring out which offer actually gives you the better value is where things get more complicated: A lower price doesn't always mean a lower total cost once you factor in shipping charges , product variations, and seller policies.
Learning how to compare prices online can help you look beyond the number on the product page to make a more informed buying decision. This guide walks through a simple step-by-step process to help you decide whether it's time to buy or keep tracking the price.
Here's a simple process to help you compare offers before you buy:
Search for the exact product: Start with the product name, model number, and SKU (if you know it). The more precise you can make the search, the easier it will be to find the same item at different retailers.
Confirm that the listings match: Check that each listing includes all the same features, like (but not limited to) model year, color, and package quantity. A lower price may reflect a different version of the product rather than a better deal .
Calculate the final purchase cost: Add extras like shipping fees, taxes, and any required membership fees, then subtract eligible discounts or coupon codes.
Review the seller and purchase terms: Take a moment to review the return policy, warranty coverage, and estimated delivery date before making your decision. Seller reputation is also important, so read reviews to see if other buyers have reported any concerning trends.
Check promotions and decide whether to purchase: Look for available promotions, coupon codes, or cashback offers that may lower your final cost. If the current price fits your budget, it could be time to buy. If not, keep tracking.
Comparing prices is straightforward when every listing is for the exact same product. It can get trickier when one retailer includes extra accessories, another sells a larger package, or you're choosing between a new and refurbished item. Here’s how to look at a product’s total value beyond the advertised price.
Compare the unit price
When products come in different quantities or package sizes, calculate the unit price instead of comparing the total price. Use this simple formula:
Unit price = total price / number of units
For example, if a 24-pack of sparkling water costs $18 and a 12-pack costs $10, the larger package works out to $0.75 per can, while the smaller package costs about $0.83 per can. Even though the larger pack has a higher upfront price, it costs less per unit.
This example is illustrative only. Actual coupon codes, rewards rates, and cash-back percentages vary by retailer and item and aren't guaranteed.
Calculate whether a bundle is actually a better value
Bundles might make an offer look more appealing, but they’re not always the better pick. Compare the bundle price with what you'd pay for the items you started looking for in the first place. If you may not use or don’t need the extras, the lower advertised cost per item may not translate into better value.
Check the product condition
Refurbished models are products that have been cleaned and fixed before going back on the market, and open-box models are products that have been returned but are in typically good working condition otherwise. These versions can cost less than new ones, even when their box was opened but the product wasn’t used. But you should still consider their potential quality differences or shortened lifespans in your value calculation.
Review the warranty and return policy
A lower price may come with trade-offs like a short return window, restocking fees, or limited warranty coverage. Taking a minute to review these details can help you avoid unexpected costs later.
Factor in membership costs
Some retailers reserve lower prices for members or subscribers. If you don’t already have a membership but it’s necessary to access a discounted price, include that cost when comparing offers to determine the true purchase price.
Understand common price labels
You may also see different pricing terms while comparison shopping. A “list price” generally refers to the manufacturer's suggested “selling price,” which is the amount the product costs before taxes, shipping, and any eligible discounts are applied. The “retail price” is how much an individual retailer chooses to charge for an item, and may be the same as or different from the list price.
After comparing products, calculating the total cost, and reviewing the seller's terms, there's one last question you may need to ask: Should you buy now or wait?
The answer usually comes down to how quickly you need the item, whether the current price fits your budget, and how likely it is that waiting could pay off. If you've found the right product at a reasonable price, you may not want to keep comparing it forever.
Buy now if:
You need the item soon: Waiting for a lower price may not be worth any personal costs of delaying your purchase.
The final cost fits your budget: You've factored in shipping, taxes, and any available discounts, and you're comfortable with the total.
You've confirmed the details: All the specific product features and policies (and any bonuses) from the retailer meet your needs.
More research probably won't change your decision: You've compared several listings and feel you've found a fair price.
You may want to keep tracking the price if:
Your purchase isn't urgent: Waiting can give you more time to see whether prices change.
The current price is higher than you'd like to pay: If you've set a target budget and price tracking has revealed that it regularly reaches a price that works better for you, it may be a good idea to wait.
The product goes on sale regularly: Some items see price changes more often than others throughout the year. But there's no guarantee a future sale will be lower than today's price.
A major shopping event is approaching: If an upcoming seasonal sale like Black Friday fits your timeline, it may be worth waiting to see whether the price drops during the sale.
Once you’ve decided on the exact product, a price tracking tool can help you decide when to buy. Instead of checking the same listing every few days, you can let the tool monitor the price and notify you if it detects a qualifying price drop. That way, you're waiting with a plan instead of constantly refreshing product pages.
PayPal Honey can help you monitor eligible products with Droplist. Just install the free browser extension to add an item to your Droplist.[1] Then, choose a tracking period (30, 60, 90, or 120 days) and enable notifications. If PayPal Honey detects a qualifying price drop, you'll get an alert.
When you're ready to check out, PayPal Honey can also test available coupon codes on supported sites.[1] And if you’ve narrowed your options to Amazon sellers, PayPal Honey’s Amazon price comparison tool can show you the differences between them (including shipping costs).[2]
Install the PayPal Honey browser extension today to get started.
How many sellers should you compare before buying?
There's no set number, but comparing prices from at least three retailers can help you get a sense of what the price difference is between offers. If you're shopping in the U.S., price comparison websites like Google Shopping Price Insights can help you compare multiple sellers without opening dozens of tabs.[3] U.S. and international users alike can access tools like PayPal Honey (availability and features may vary by country).[4]
What should you look for in product reviews and ratings?
Look beyond the overall star rating. Recent reviews may reveal whether a product performs as expected, whether shipping was reliable, and whether buyers felt they got a good deal. If you're shopping for a coffee maker, for example, reviews may highlight durability and ease of use.
How do you set a realistic price target?
Start with your budget, then compare current prices and any available price history to see whether today's price is typical. If a major shopping event like Black Friday is approaching and your purchase isn't urgent, it may be worthwhile to wait. Otherwise, buying at a reasonable price (whatever that looks like for you) can still be a smart way to save money instead of holding out for a discount that may never arrive.
