My problem is mostly that I shop in three different places, and usually shop only once a week.

I mostly rotate between Trader Joe's and my local co-op. The co-op sometimes carries the white whole-wheat, but I've had times when I've gone in and they haven't had it.

And then I also go to Rainbow (one of our big chains) maybe once a month for stuff only they carry. (bottle of lemon juice, which I put a little in drinking water, for example. some kinds of frozen foods. Etc. etc.) But since I'm not there as often, it can be 3-6 weeks before I get there again.
