Good morning. I've bought two Open Box items from them. My Late 2009 iMac 2009 27" i7, and a 24" iMac. I never had an issue with either purchase or computers. I didn't have an issue with Applecare, since the models I bought were the current models.
I'll aways try to buy from them first, since the price is very attractive. I was able to get my maxed out 27" i7 for $1500.
