... I guess the answer is no. Sooooo Any possibility for $15 and $20 Gift certificates being available? There's quite a long way from $10 to $50 :(

Can't - or won't ... anyone answer this? ?

There is no way to use two of them on the same order however you can get gift certificates combined by asking on the Customer Support Forum. It's usually pretty quick (same day anyway). So you can get two $10 ones and ask that they be combined into a $20 for example. You can also combine all the leftover pieces of partially used ones.

Thanks for the reply. :)

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.
