There is a more effective way to hustle these promos.... Some usually fairly attractive girl is standing in front of the casino, passing out $5 Matchplay coupons, you take one, then maybe another one.
Flirt with her,tell her you like these....offer her a $20 tip (bribe), with some class to give you 50-100 of them...she gets rid of them, you get them...play anything, at about 10 tables, return later.
