Has anyone thought about offering free vacs for SS bay users if the customers spends $5 or so. I'm not very technical, but I'm sure something could count the pulses up to the $5 mark then offer to dispense a free token. I think this could really be a hit, but probably wouldn't be worth the expense. The only way I could see doing it is using the Carolina pride token dispenser in each bay and that over $2k per bay. Any thoughts? Free vacs seem to make all the difference in the EE sector
