We've been covering Prime Day SSD deals for a number of years now, and we only ever report on genuine savings on trusted drives. But we don't want you to just take our word for it. There are free tools that can help you make sure that you really are making the best buying decision when you see a deal that looks good to you (many of which we use).
Top of our list are easy tools that will allow you to see the price history of the product that you're thinking of buying. Google Shopping is good if you want to compare information of products, and the big one for Amazon (which we use all the time), is CamelCamelCamel. You can use the site, or get a browser extension, which will make checking the price an easy one click exercise.
