there's no way someone can afford to give away good stuff at 50%
There are LOTS of ways.
Some businesses this works for, some not.
Think of a wall climbing place.
The lights are on, the equipment is on site, the staff members are there. It doesn't cost them more money if the place has 2 people climbing or if it has 50 people climbing.
Their cost doesn't go up with each person that walks through the door until they reach a certain benchmark.
For businesses with fixed costs these coupon services are great.
