I didn't really mean "trade-in" in the literal sense, but since you asked... I don't know if Target takes trade-ins, but Best Buy will sometimes.
In January, BB was giving $5 credit towards Blu-rays for each DVD you traded-in. And I think they're doing a similar deal on games right now. (They also have some kind of buy-back program on their website which I haven't tried cuz it looks overly complicated.)
There are a couple video stores in my area that take gently used discs for credit or cash though, so I might unload the EC there (or just wait for another BB promo).
It's a High Hide. A High Hide... See you go up and you hide, high. It goes up to where the trees are, and keeps the researchers out of harms way.
Actually, it'll put them at a very convenient biting height.
