I buy a dozen eggs for $3-5 in the middle of San Francisco. If your wife is paying double that, that too for bulk orders, then she is definitely doing something wrong. She can literally shop at Whole Foods and save money.
I've seen egg prices all over the place in my area. Ironically, the high end stores seem to have lower egg prices right now. I'm guessing the huge industrial type farms are getting hit hardest while the smaller farms, offering true free-range and other marketing gimmicks are largely business as usual.
