Discount Code applies to cart successfully but doesn't do anything. Am I missing something? Standard 10 dollars off discount setup.  Although it says it is applied, it doesn't give me any kind of a discount.  None of the discounts work, I've made multiple and tried different options but it still doesn't work.  Any ideas?
The reason for the discount not being applied is that nearly all your products have not been marked as promotable (by looking at your database):

No sales or discounts can be applied to a non-promotable product.
