What's the point of having to choose a percentage? I don't know the calculations in my head, and usually go based on price. What is the point of making us enter a random percentage, just to see what the value is on the next page? Please let us enter the value we want to offer, instead of having to guess what percentage we need to match the price we really want. This effect doesn't seem to be on all listings, but its very useless as most people cant calculate the percentages in their head.
