Best Buy is now offering a trade-in program for older generation Surface tablets just in time for the launch of the next generation of Surface devices later this month. You can trade in a Surface RT or Surface Pro tablet and get a gift card worth at least $200 and up to $350 which you can use to buy other stuff from Best Buy. You need to visit the nearest Best Buy Store to use this offer. The program will end on Oct. 21.
