So you CAN use the coupon in the store, but because of the emailed list of ineligible items you probably won't be able to use it on what you want.
HOWEVER, the code will work on just about everything on the website, because apparently the email didn't hit the web design team. LOL I just ordered two pair of shoes that I was told I couldn't buy in the store, and I had to pay S&H, but it was still a pretty nice deal.
So, if they wont' let you buy the item in store, use the online codes and order there.
YMMV (The code will work on their register, but the reps at the store won't (aren't supposed to) ring it up for you that way. So you might be able to argue through it.)
