I noticed while using the new cart discount feature that I cannot enter a flat rate for shipping discounts -- only percentages. While I know that I can enter 100% to give a customer free shipping, it would also be great if I could enter a flat rate discount for shipping so that it won't exceed a certain dollar amount (for example, I'd like to offer a discount up to $3.99 so that US customers get free shipping, but international customers or those wanting faster shipping must pay for the difference).
Whenever I indicate an item discount, I can freely switch between % or a flat rate. However, the moment that I switch from Item to Shipping, it forces me to only use a percentage value.
Please let me know the status of this feature and if it will be changed or fixed in the near future. For now, the 100% discount is working okay, but eventually I know that someone will order from another country and I'll have to request additional shipping fees from them instead of just having my shopping cart take care of it.
