Hi.....I have been playing on and off at casino grand bay for about 2 years now and I never knew about the bonus codes.....but I also have cashed out over 1200 on 2 free chips I got thru the mail from them and had the checks in 7 days. Lots of casinos have changed the way they are doing promos I have read on different forums about folks that are having the same problem so dont feel alone.
