OK the whole coupon thing is crazy/broken as far as trying to figure out what works and not for coupons. I am attaching a series of images below. The first shows a example cart of one item that does not allow coupons (rightly defined in the red box) and 3 other items that all appear to allow coupons, see green tags...

I try the coupon and nothing, no feedback, no indication there is a problem, just no discount??? I go back and pick another item, and add it, and then reapply coupon, and WOW! All of those items now inform me that coupons do not apply now? Then I have to go back and read, and find out that anything Prime is not allowed...wasted a lot of time this morning. :(

Now I think... Well, maybe I need a "NOT Prime" account as well, since sometimes deals are better for sale items with coupon. For example, Messy hair on Sale with 20% coupon is $5.17, versus Prime $5.83. So, I asked my friend to try, since they are NOT Prime, and the Veterans Day coupon does not apply to any item that is Prime for them (even though they do not have Prime)

Ugh...whole thing is very difficult. Rant over, maybe something the web guys can look at that things indicate when coupons do not apply in the right places.
