I love the products, but
I love the products, but become frustrated when I'm given a discount, only to find that the products prior to the discount had free shipping. The discount then incurs a shipping fee, so from my perspective it's not a discount. A discount is a discount, full stop, end of story! I shouldn't have to spend more money to make a discount work - it's a contradiction in terms, if I'm using more money for a discount!
Your products are good, but they're not cheap! Give your customers a break, please.
