mods can delete this if they want , not sure if this is appropriate BUT
if you can buy both season 5 & 6 for 30 or so and you dont even like the show. . .then dont open them and hold on to them for 11 months, right near x-mas, then you can return them for store credit at 39.99 a piece, so thats 80 bucks, so your profit would be 50 and you could buy whatever you want with it, =D
dont worry, i use to work at best buy and pwn them
