> Quote - Have you ever considered letting people have the option to buy sale items for full price when you have a coupon that does not apply to sale items?  In many cases the items that I am interested in and that are currently on sale are discounted much less than the 30% coupon.

That would then leave vendors with no way of opting out of the higher discount coupons (see attached link) as putting items on sale is the only way they have of stopping the coupons being applied to their items (which is why a lot of items are on sale at low percentages this weekend).
