Went to Costco in Henderson on December 12, 2012 and was able to purchase $100 worth of gift cards for $79. I haven't checked the costco.com website. The cashier at Costco even remarked it was a good deal. I bought $100 and was able to cash in at checkout desk. They can be used for anything on the property but I applied it to my bill. Be advised that they only have 1 gift card reader in the checkout and it seemed to take them a long time to do it but it got done. **cards are also good at the AC Golden Nugget location also.
