Do you have some spare gadgets laying around? An old GPS, maybe an old Zune or camera? Why not trade them in for a gift card. Several stores offer this already, but now Amazon is joining them by adding electronics as their latest category for trade-ins.

All you need to do is choose from the 2,550 items currently recognized and describe the condition of the gadget and Amazon will let you know how much credit it can give you along with a prepaid shipping label. It beats throwing it away right?

Japanese retailer Enterking has announced that it will not accept Nintendo 3DS gaming consoles that have been used with a hacked memory card for trade-in. So how will the retailer will know? Simple. Because the portable gaming console logs all activity, which can then be retrieved by those in the industry who know how. It is an attempt by Nintendo to deter pirates.

The most common card used is the R4 and some Japanese hackers can already install illegal DS ROMS but not games. Since the system keeps track of any and all hacks and has a Wi-Fi connection, it could also let Nintendo block pirated devices from accessing online services and games.

Warner has a new trade-in plan that hopes to convert you to the ways of Blu-Ray (Especially if you just got a Blu-Ray player and have a ton of DVDs, they want you too.) Just send in your old DVDs, $7.95 to $9.95 per movie plus $4.95 for s&h and HD versions will arrive in about 4 to 5 weeks.

You’ll have to decide if it’s worth it or not by consulting the 55 movies on the approved list that you own, but we suspect that most of you will just want to keep the ones you have on the shelf and wait for better deals.

If you have been a gamer for a long time like I have you probably have games stuffed in a box somewhere for consoles that went obsolete years ago. Somewhere I still have a box packed with games for the 3DO. If you are tired of those old games hanging around, Toys “R” Us has a new program that will help you get rid of them.

The toy retailer has announced a new trade-in program for video games that covers more than 25 different gaming consoles including classic consoles like the Atari 2600. The trade-in program also covers new consoles like the Wii, PS3, and Xbox 360 as well.

If you recently jumped on the Blu-ray bandwagon, chances are you’ve got a bunch of DVDs that are pretty much useless now. Warner Bros. wants to help. The company is now offering a trade-in program called Red2Blu that allows people to trade in 25 Warner Bros. HD DVDs and have them replaced with Blu-ray versions.

The new program isn’t free though. It will cost you $4.95 per disc plus $6.95 for shipping on each DVD. Interestingly, you don’t have to send in the discs to the WB, you just need to send in the cover art for the HD DVD discs you want replaced.

If you’re like me, you don’t like spending $50 on a game only to beat it in a few hours and have it sit on the shelf forever. That’s why I resell games or trade them in, so you can get more for your money. Sadly Gamestop’s trade in prices often suck. Well, good news.

According to Webware, Amazon will now buy back used games for more money than Gamestop. Amazon launched the service today, and they currently accept over 1500 titles across platforms. Webware compared some of the bigger, recent releases, and it looks like Amazon offers $2-$3 more for games on average. Shipping is even free. Thanks Amazon. Thank you for caring about my wallet.

Best Buy has made an announcement that it truly does feel bad for all of those that bit the bullet and made a decision in the high-def video format war, before it was over. People wanting high-definition video last year and early this year had a tough time making a decision between Toshiba’s HD DVD and the Blu-ray formats, and some chose the wrong one.

Now that Toshiba has stopped making the HD DVD formats and studios have stopped creating HD DVD formatted movies, the players are almost useless and Best Buy is recognizing this by offering a $50 store credit to all that purchased an HD DVD player from Best Buy before February 23, 2008. Some will automatically receive the checks from Best Buy, but if you don’t get it by May you can call them and request it at 1-888-BEST-BUY.

You no longer have to skulk in dark corners and whisper the secret password in order to trade in your HD-DVD for Blu-Ray. According to the AP, the electronics retailer is officially launching the promotion. Circuit City will be accepting returns of HD DVD players within 90 days of purchase, with a proof of purchase receipt.

Customers can receive store credit or use it toward the price of a Blu-Ray player. Circuit City will definitely be scoring some customer goodwill points with this promotion. Great move. Now, all you HD-DVD buyers have to do is find someone to buy your movies.

Now there is another place that will take your old game console, if it’s collecting dust in some closet. Best Buy is willing to take it off your hands. One thing though. And it’s odd…This new service won’t let you just drop off your old hardware at the local store. You have to ship it off to them.
