Glad you have got it worked out.
Sams does sell smaller versions of "bulk" items, no need to buy a single huge can of Tuna, instead many items they sell multiple smaller cans.
For instance, we like canned chicken to make homemade noodle soup, or Chicken Salad sandwiches, they sell that in smaller 12.5 oz cans. They however are bundled and sold in a "six pack". The good thing though is canned items have pretty long shelf life.
We buy all of our ground beef, steaks, pork ribs, boneless chicken, chicken quarters, porkloins at Sams, we divide up the meat and vacuum pack and freeze. Much cheaper than our retail grocery stores and the meat is fresher also.
Things like cheese we buy a large brick or package of slices, divide and vacuum seal and it will stay fresh for many months in the fridge.
Pretty much our go to place for green grapes, apples, oranges for fresh fruits, started buying stuff like salt, pepper and other seasonings at a far cheaper price than retail stores when comparing cost per ounce.
Granted, not everyone likes to stock up like a "restaurant" for season but for us it works great.
Quite a few yrs ago when Sears started going out of business and closed our nearest store I found that Sam's automotive batteries were a better deal and the quality is above par from the old Sears brands.
Never tried Sam's for tires but I suspect they are priced competitively also.
