I'm moving from US and am wondering if it would be worth keeping my Costco membership. I understand that there is a Costco in Seville (Spain), and was curious to know if anyone has used this place? How easy or difficult is it to go out there and buy things, is it worth the effort? Or is it useful to order things online with them and have them shipped to you? Please share your experience, appreciate any feedback you might have to share!
