It may depend on where you go. I was at the Riviera on Saturday and went to what I thought was the slot club booth to sign up and get my free chip. They signed me up for the slot card, but when I presented the coupon for the chip they told me it was only good on Thursday and the promotion had ended.

But at the promotions desk they had a box with many chips in it and they told me that they were still giving them out.
