There are many nonfood items you can get at Costco at reasonable prices that I did not include; this is strictly for food. If you are still on the fence after seeing the food and expenses, then make a trip there or look online at all the extra stuff you get with the membership and other things they sell.
I just took group pics in some sections, like the freezer and refrigerated items, because it was easier; you can probably blow them up to get a closer look if needed.
I also did not include certain items that you may actually use in your diet that I and most others don't; they sell many brands of jerky, nuts, dressings, vegetables, and sauces that contain or are cooked in vegetable or seed oils, I personally avoid these but if you don't then they have these too. I also did not take pics of most of their meats. They look good, but they are not that cheap compared to most grocery chains.
In my opinion, Costco does have more clean keto low carb options to choose from; the membership is more expensive than Sams club. If you have both clubs close again, I highly recommend you visit both and decide for yourself which is best for you, I only have a membership to both because You can easily find discount Sams club memberships on Groupon, where they basically pay you for the membership, so I really only end up technically buying the Costco one. Once in a while, there are also Costco discount memberships on Groupon. Below are My findings; I hope they help you decide which club to choose or give you a shopping list.
