I need My Card

I went with my sister shopping in Las Vegas. This happened last year as I went to the US for a two months vacation..I miss that place especially Vegas. Hello Vegas, I truly miss you!! Shopping in Las Vegas is really fabulous and exciting! well if you have a lot of money. But anyway, I was just amazed how many shopping cards she has. One membership card, I remember was in a hotel where we had a buffet dinner. You cannot enter in the buffet room if you are not a member. She also have cards for Walmart, Victoria Secret, Cosco and some other shopping cards. Beside that you can also earn points, you can also have sometimes great deals and promotions if you are a member!! isn't shopping more interesting!! I hope to be backed in Las Vegas next time. I know for sure but I just don't know the exact time! I always need my card if I go shopping in Real Supermarkt to earn bonus points..not bad at all!!
