<prompt> Human: I own a tobacco shop, so I spend about 10,000 a week on average at Sams Club on tobacco. Last year I got the Sams Club credit card because they offer 2 back on purchases, which sounds awesome to me! I just purchased my cigarettes every week using the Sams Club card, and then paid it off completely the next day. Which means about 200week in cash back! Pretty decent if you ask me, especially since I only make about 1carton profit on smokes. My problem is, Sams Club has been slowly lowering my credit card limit, from 11,000 to 10,000 and now to 9,000 all within the last year. Also, they capped my cash back I dont remember the exact number but its something like 1600 which means I use up my cash back incentives after only 8 weeks... Can they keep doing this??? What if they end up lowering the limit until its at 3,000 or something?Also, Sams Club doesnt accept American Express unfortunately... otherwise I would be taking advantage of that instead lol!Any suggestions?? I spent a lot of money on items I dont really make any profit on, so most of my profit on cigs is through gaming the system like this...  <response>: Do you have a Costco nearby? Vote with your wallet!Also, 10k a week and you cant work directly with a distributor?
