We get all the basics from park n shop and wellcome and then get western goods at oliver's, 360, gateway, etc.
My husband is the world's pickiest eater, we go out about once a week, and I spend about 600 at park and shop every week or two, and about the same at some combination of oliver's/360/gateway/great/taste/city'super, though we spent more at first trying to find what we liked and finding where to get it, and I am pregnant, so there were times I just HAD to have whatever it was i saw at the western type stores. Now that we have a pretty good set of recipes it's easy to keep things stocked up at home, and we buy more from park n shop than the specialty stores.
