When I started Act One in 2011, we ran a Groupon for 3hours/$50. It made the phone ring while I got my sea legs, so to speak. That offer expired in November 2011.
Four weeks ago we had a lady try to claim it after scrounging it up on the Stinkernet. "But your Groupon says..."
"Yes, dear, but it also says that it expired 4 1/2 years ago."
Since that first coupon we've avoided training customers to wait for a sale, but I do offer AMAC seniors a discount. Angies List members get 10%, active duty might get 100% if I like them and vets, churches, widows and sometimes others get accidental breaks as needed. Do what makes you feel happy.
