You still have one day left (7-13-13) to head to Best Buy where they are offering $200 or more in trade-in value when you trade in your iPad 2 or 3rd generation iPad. You can opt to receive the trade-in on a gift card or use it to buy a 4th generation iPad.If your tablet is in really good condition you can get even more money.
I would check online pricing for your iPad on Amazon and eBay just to be sure you’re getting your maximum value. You should also take the connivence of getting your cash immediately into consideration as well.
It’s likely that BestBuy is trying to clear out some of it’s inventory ahead of the release of the anticipated iPad 5 this fall.
