Eversave Philadelphia. I've used their certificates a few times and all went smoothly. Here are the two currently in my possession:
1. A certificate worth $20 at Mugshots Coffeehouse and Cafe -- three locations in Philly (expires 5/30/12)
2. A certificate worth $15 at Steaks on South -- on, naturally, South Street (expires 2/29/12 -- it's an older certificate so there's not as much time left to use it)
I'd be willing to give one or both of them away in a contest. I have an idea for what the contest will entail. What I need to know is, is anyone actually interested? I don't want to waste the time and effort if no one enters. Unfortunately, since they're both local establishments, I assume it wouldn't be of much interest to out-of-towners. Maybe if this works I'll hold another one, with something like an Amazon gift card as a prize.
So let me know -- either by replying to this post, or via Twitter or Facebook -- would you like to win one of these certificates? (And if you reply here, please don't post anonymously. Use your name or nickname or something.)
