Check your Foundary Account you may have a $10 or $15 credit waiting for you! I got an email stating this:
For making the Foundary a place to call home, we’d like to extend a gift of $10 in Foundary Credits to you, redeemable at the Foundary by May 31st, 2011. Simply log in and start shopping to use your new credits.
Some people are reporting a $15 credit being added to their account and some are reporting a $10 credit, let me know what you got!
