Amazon Discount Tool
Use the Amazon Discount Finder For UK to find best disocunt deals on Amazon.
When searching for products, don't just look at the first page of bargains, try a few. And don't assume just because it's discounted it's a good buy. Try higher percentage discounts for cheaper, smaller items and lower percentages for niche, expensive ones.
This search isn't perfect and can produce odd results. We will continue to try to perfect it.
