Deals!

It's hump day, and we think you deserve some deals for getting through half of this week.

• $25 for a membership to the National Building Museum at LivingSocial.  (Usually $50.  At the $25 rate, membership makes sense if you plan on visiting 3 or more times.)  You can also snag membership to the new Keystone Society (for "emerging professionals" looking for "unique educational, social, and networking opportunities.")
• Buy a Greek froyo get a Greek froyo half off at Ben & Jerry's (valid for all of June).
