memory upgrade

Has anyone used eshop mac sales.com "OWC" (other world computing), for memory upgrade and used their "memory trade in rebate"? I can buy 3.0GB (1GB+2GB) for $75.00 and then return my 2-512's and receive a $35.00 rebate.
To me it seems too good to be true.

OWC is a great place to buy RAM. I've never purchased RAM from them but have purchased other items from them. They're GRRRRRRREAT!

Thank-you photoguy, I will give it a go.

Yea, I saw that trade-in offer last time I visited the OWC site. I thought how great that is to get actual cash back for memory you can no longer use. No other company does that as far as I am aware.
