They don’t ask for a membership number, but they have a 5% non-member surcharge, I didn’t realize that. But fun fact, Target price matches with Costco and I’ve saved lots of money combining that with their redcard. As long as it isn’t a member-only item, you can price match.I assume they’ll ask for you to login to an account with a valid membership to check out.
It even says “limit 2 per member” on that page.
