This past Memorial day weekend and a few days earlier I tried using both of those codes and they dodn't work for me. I went back the next day and the rena xp3 I was going to buy was sold out. Since the codes didn't work I bought it elsewhere. Having said that, my order was reduced to just over $75 for free shipping and is on the way. I will still buy from them though. They do have the best prices, however, IMO the shipping takes a day too long to get to me and they're only 500 away. It shouldn't take 5+ days to get to me!
