  1. I have had no luck executing an Instacart food delivery order from your warehouse in Westbury NY 11590.
    WHY? Because at the end of the order, on my computer screen there is a box for a number. I entered my Visa credit card number and my member number — neither was accepted. Can you tell me what number I am to use, I’m missing a lot of good stuff because I have to order from a store that has very limited choices. Thanks for your help!

  2. I simply am trying to find out how long this mask order will be in effect? I am not wearing a mask…I am careful…I sanitize everything…and I am NOT wearing a mask. I truly love your store, but will not longer shop there until I need not wear a mask. I am also a senior and am trying to find out if I can ONLY shop during senior hours??? Tried that once and it was a circus. I will return to Sam’s today to get the things I need and think about whether or not we need to continue with Cosco.

  3. We had a patio set delivered Saturday, May 9. The table top is damaged and I cannot seem to reach anyone to discuss this issue with.

  4. Just wanted to say I thought that Tison did a wonderful job with the customer that would not wear a mask….I do not feel comfortable going in a store with people not wearing a mask….thank you
