Have you heard about DVD2BLU.com? It is a site where you can send in any DVD (no adult content) that is produced by any studio/sold at retail stores or online and trade it in for a new BluRay for just $4.95. BluRays normally cost $20-25, so trading in an old DVD you don't watch anymore for a BluRay for under $5 is a good deal! I know we have some old kids movies scratched beyond any hope of playing that would be great for trade in.
There are over 100 BluRays available - so there's a good chance you'll find a movie you want. We have a PS3 with built in BluRay and the picture quality is just phenomenal on your HDTV. The difference between normal DVDs and BluRay is really remarkable. So this could be a good time to trade up your old copy for a BluRay and enjoy the immense difference in picture quality.
Right now, there's free shipping if you order $35 or more. Normally, shipping is $4.95 each, so there's incentive to trade in a stack of DVDs. Check out the program rules for instructions on how to send in your DVDs.
