Best Deal on Full Metal Panic Complete Collection (Thin Pack)?

[animemaniac14]

I've been trying to find this series REALLY cheap for a while and im not sure where is the best place to find it for under $50. anyone help me out?

 

[freonchill]

iirc i got it from best buy for $48 but it looks like they raised it to $58
bb seems to send out the 10% or 12% coupons all the time these days - that will get it down to $51

cant find it online for cheaper...
