As a frequent visitor to Las Vegas, I long ago acquired a shoppers card and always purchase a number of discounted gift certificates for each of our trips. I normally make my purchases during the quarterly marathon shows or whenever they run one of their periodic sales events. Purchases may also be made at their offices during regular hours. Most of my purchases have been for restaurants, shows and personal services such as massages and haircuts. They have an online shoppers guide which is quite helpful. Be aware that unless otherwise indicated, certificates are good for only 90-days. Should a business go out of business or otherwise not accept a certificate, you will receive a refund in the form of a credit.
