My shopping cart is still full, but I hate it when a discount doesn't work. I know C4 will get it fixed, but I don't have time this morning to get it sorted out. I'll send them an email and then call if no response. Maybe it's just too early in the morning for the code to work.
Let me know if you use the code and have better luck than I do. Until then, maybe it's the Universe's way of telling me that I don't really need to add to my pile of belts. My husband would agree.
