It's expensive but cheaper than mail ordering stuff myself. A lot of what I buy I can't find at local grocers. Like yakisoba sauce. >=/ No one around here has it! I hit up a tiny asian market called May Jean's, but they were sold out. Go figure.
I have at times considered mail ordering food stuffs
but then the shipping is just not worth it. It would cost the same or more in the end.
Then again I can find almost anything I need at either dominicks or whole foods. And if I really needed something odd, there are plenty of ethnic grocer's in the area
