There isn't that much in the stores I would really miss - everyday more "imported" items are showing up on the shelves, for a price of course. If I had a home in JA, I know I could count on visitors to bring me some little things or I could ship myself a barrel once a year. I would definitely look to grow a few things in mi yard - if possible. But all in all, as long as I have internet and/or a Kindle, I would be fine for at least 6 months of the year.
