sales, percentages and coupon improvements for MarketPress

– Sale Price: does this field take an amount or a percentage? (I guess it is an amount)

– would it make sense to be able to enter a % in the sale price field too?

– how about being able to tie the sales price to a date range after which it simply gets reset? useful for winter sales for example

– how about being able to create coupons for certain categories, i.e. a 10% discount on all products in my ladies underwear category?

– how about the ability to mark coupons so they only work on the normal price not on the sales price and vice versa?
