this is the 3rd time i try to use a coupon code that I got and it was not correct , the last 2 times I lets side but this time i need to bring this to someone attention

The coupon was for 10% for any purchase for $10 or more. see screen shot 1 when I added my $11item from my wish list i got a error stating that the coupon is only good for items c$15 or more. see screen shot 2

this time i took screen shot to prove I'm not nuts. and t this kind of thing is that keeps me from buying things.

I live in Tennessee so any 10%off coupon just barely cover the cost of the sales tax I must pay for living in Tennessee when purchasing stuff here. which has become very rare because of this 9% TN sales tax I have to pay.. so when I get coupons that don't work its very frustrating. to say the least

Can renderosity please view my screen shots and please fix the coupon thank you
