I once had a membership at Sam’s Club. I found myself less and less willing to renew membership because I just didn’t feel that it was the best deal for me. I was put - off by the fact that if you happened to purchase something that was not packaged in a carry friendly way, Sam’s did not feel compelled to provide a bag or a box. There were times when no boxes were at the check out. One of my last, if not the last time I shopped there I purchased over a dozen canned products. It was a nightmare getting them stacked securely and then out of the store and placed in the bed of my truck for travel. I prefer to shop where they are willing to provide stuff like bags. As for buying garbage bags or something to use… that is a great idea if you already had those in your basket. If you did not have them in there then you would have the inconvenience of stopping your purchase, getting refunded for the items already scanned, going back into the shopping area to fetch bags, and then getting in line again. I am not surprised that Sam’s does not offer bags for the customer. This fits into their business philisophy perfectly. I also felt put - off by the search / scan before you leave the store. I understand the reason for it but nobody else does this so it seems unusual… or at least I don’t shop in any other stores that search or scan your stuff when you leave …in this intrusive way.
I do not think it unreasonable to ask for a bag from Wal-Mart and it think it is unwise for them to refuse. It kinda makes one want to go to Wal-Mart and buy a few cheap items, request that they double bag, or insist that they only place three or five items per bag. I suppose the decision-makers would then write a store policy on double bagging, etc. Perhaps they already have a policy on this.
