in the long term it is absolutely worth it. for example you can get a bag of lays potato chips at sams club that is bigger than the largest size they sell at regular stores and its cheaper. like im talking regular large bag of chip at a normal store= 6-7 dollars vs the sams club bag being like 4 dollars or less if they are having a sale.
i also recently started buying my laundry soap from them as well which i was iffy about because its pretty expensive but once you realize that jug of soap is going to last you for literal months if not the whole year you start to see how worth it it actually is. stuff like paper towels and toilet paper is good too.
if you have kids or just enjoy chicken nuggets a bag of tyson nuggets is cheaper than normal stores and larger as well. overall the way i handle sams club and club type stores in general is just browsing what they have either online or in store then comparing whatever i look at with how much it would cost at the store i normally buy it in along with how often i actually even use that thing.
im not going to use what is essentially a bucket of peanut butter before it rots but i use ketchup and mustard a lot all year round so its worth it.
finally i cannot compliment their baked goods and prepared meals enough. some are very hit or miss but if you have a family to feed and you want a nice quick meal buying a rotisserie chicken is an easy solution along with some cinnamon rolls if you want a dessert.
