Funny, I just saw a businessman doing something like this today. he bought almost 15 3DS's and got a bunch of giftcards... I'm assuming it was probably the 'buy a 3DS get a $50 gc deal'. I bet he's gonna flip it on cg/fleabay... highly doubt he has 15 kids to gift them too
He was probably buying them as corporate gifts for his company.
Back when I worked at Best Buy, several corporate managers came in and bought cartloads of Wiis, iPads, small HDTVs, etc. to give out to their employees.
Clearance seems to have dried up in my area for the time being.
The only thing of interest I've seen/picked up is "You Don't Know Jack" for DS for $8.98.
