Coupons general question.
I'm not sure what the coupons feature is, or how it works, so please bear with me while I ask a question that probably everyone else knows but me.
If I enable coupons, how does a customer use them.
For instance, can I offer coupons for discounts in posting ads? Can more than one coupon be offered at a time.
Or, if I want to give someone a coupon code to post a free ad and bypass the paid ads, can I just send it to them by email?
I've read all the coupon related threads, but am still in a bit of a fog over this.
