Will you convert gift certificates into store credit?

The renderosity 'gift certificate system' doesn't work nearly as smoothly and seamlessly as the company's store credit set-up.

Whenever I can get a fair amount of store credit I try to combine it with old gift cards that have random amounts on them that people can't otherwise use. I fill in any funding gaps with store credit. Renderosity makes out because I tend to buy more with monies that would otherwise probably be left to the gift card companies.
