Power up reward pro members (14.99 year membership fee) can print out an online coupon, take it to a store, trade in a dslite, dsi or dsxl and get a 3ds for 99.00.
this is specific to your account. i got something a few months back on a ps3 for $200. no one else i knew knew with a pur account got the same offer. I'd jump all over that one.
You have to login to your own account and the coupon is under active offers. I called gamestop to ask if I could trade in more (we have a dslite, dsi and dsxl) and yes, you can. He said the sale would be to all PUR pro members. You might want to check with your local game stop.
