Best Buy disappointed me all year this year. TRU was less than impressive, which is sad, they rocked the year before. Targets around here are always wiped of clearance (and by wiped, I mean everything is stolen, and their LP department couldn't give a flying fig over this... and that makes blood shoot out of my eyes). Kmart, I've done okay on their clearances.
All in all, I have to go with EB. With their trade-in bonuses and weekly coupons, I've been very happy with them this year.
