Amai Bulk Discount & Sales

There are a lot of quirks with this app. You would expect to enter 40% in the discount field and it would calculate 40% off. Instead, it MULTIPLIES by .4, which is 60% off. I could get used to that, but then it applies an ADDITIONAL discount to the sale price if something is already on sale, rather than replacing the sale price. It also takes a long time to run with a database of nearly 10,000 products. The app might be fine if you can get used to it's quirky rules, but it was not for us. We literally sold some products at a loss before we realized what it was doing. Documentation also weak.
