Hi! Im going to a job interview on Mountain View and I would like to buy a 13 inch MBA with 4GB of ram, 128GB SSD. Ive just found that I cant buy it on us apple store and ship it to my hotel address ( coz my cc billing address is from Brazil). Is there any way to get a MBA with 4GB of ram in retail stores? Thanks alot. BTW, do you know stores like best-buy that accept intl orders?
