i was at a sams club in tijuana mx and they were having a membership promotion i was told that the membership was good at all sams club stores and online. so i purchased a membership and since then i have had problems using it at the san diego store i have been back to the store where i got the membership several times now i have tryed to set up a online account and my membership number is not recognised so i called customer service and was told to set up account on sams mx site and i would be able to order online from san diego store. so i did but i am unable to select any store outside of mexico. so i called customer service again and was informed that if i want to make online purchases at san diego store i would need to purchase a sams club membership in the usa. i am disabled and need to be able to use the curbside pickup but i dont find it acceptable to have to buy a second membership to do so.
