about 15 months ago, I played at one of the large downtown reno casinos and took about a $6000 loss. I was getting monthly mailers with $500 in chips, room, plus restaurant credit. I was finally able to take advantage of offers, two months in a row. No problems, but since they had also told no more bj, I used chips at craps table with no card. So officially, I gave them no action. It looks like offers finally stopped. Which more lkely:
a) by taking offer and giving no action, it triggered them to stop sending offers.
b) after 15 months with no action, offers finally stopped.
