At Harrahs (or Rio) Las Vegas cashback requires 4500 total points to get a
bounceback check of $10. Those points must be accumulated in 1 month. If you
accumulate 2000 points in June and 2500 points in July you get zip.
Cashback checks are good for at least 6 months.
Other casinos may give different sorts of cashback. For example when I
visited New Orleans the bounceback check I received had to be redeemed in about a
month or it was void. For Lake Tahoe I got a bounceback check of some sort,
but then for months afterwards continued to get other cashback checks of a
lesser amount. These all expired within about 1 month.
You cannot cash your checks just anywhere. For example cashback at Las
Vegas or Laughlin can be cashed any of those locations. Tahoe cash can only be
cashed at Tahoe or Reno. New Orleans cash can be cashed there or at a couple
of other casinos in the South (Tunica is one I believe).
Ask your local casino about their cashback policies.
Also some Harrahs issue 2X or 3X point coupons. Vegas never does.
