member to both;
costco has higher end stuff
bught my computer there cause if a problem arises i wipe and
return cause it is a membership with benefits

sams is fine for water, peanut butter , i can never find clothes i'd wear or similar items but overall it's fine


either way be prepared to buy large stuff which generally costs more and a bill that is a hundge or better,
if you are single it is not worth it imho
