Well, I did get my two hanging baskets, but it took
forever for the cashier to figure out the coupon. She had to call two people over and they even called another HD to ask how to input the coupon! When they scanned my coupon, it came up that coupon had already been redeemed, even though I printed out the coupon just 30 minutes before. Not sure why it was scanning that way. They ended up manually taking one of the baskets off as a coupon.

Anyway, it was worth the hassel.
Edited to say that I just read above posters comment. The linked coupon above has already been redeemed, right? How to you get one then?
