Ignoring Offer Listings
Amazon provides more than one offer for any given product, you just have to look for them. On a product page, you’ll see the price in red. However, below that will be a link for additional prices, featuring both new and used versions of the same product. Click that link and you could find some great (or at least better) deals.
You Forget About the Seasons
If you’re on the hunt for seasonal products, you can save some cash by timing your purchase. As CNBC notes, try buying a grill in the winter or a new vacuum in April, right before spring cleaning season. Amazon consistently discounts items that are either out-of-season or right about to come into the season. It’s your job to make sure you’re shopping at the right time.
