They offer a 20% coupon if you give them your email. It seems like a good deal at first. When you get to your order page (shopping cart) you see the 20% off and a delivery charge (it didn't say there would be a delivery charge, but I expected it). Then you go to the payment page and enter all your info, card number, delivery address, etc and when you click confirm, you get to the page that actually has the total they are charging you. My total was $20 more than what it said in the shopping cart. I complained afterwards in a chat and they said sorry for the inconvenience.
