Are one-time-use deals allowed?
A coworker just notified me about an online retailer that sent out some really good coupons via their newsletter. Each subscriber gets a one-time-use coupon for savings, so obviously there's no code for me to post. Posting the deal would be more of a, "Hey, look at this!" kinda thing. I was certainly happy to find out about it.
