I have quite a few friends who have had babies recently, or are having them soon. I haven't bought anything for myself from Mamapedia but I've forwarded lots of great deals to friends and have bought a few deals to use for baby shower gifts. If you're reproducing you should definitely get on their email list.
I paid $30 for a $20 (printed on ticket) ticket to a show at Radio City. I sent numerous emails to complain, from my own email and also from their "contact us" email. Nothing. Not one word. It has been over 2 weeks.
