Just go to April Gourmet. The prices are usually on par with places like carrefour.

For most imported foods, Jenny Lou's (or Jenny Wang's as it seems to be called nowadays) is much cheaper than April Gourmet. For example, Post Pecan Nut cereal costs 32 rmb in Jenny Lou's while it costs 39 rmb in April Gourmet. I've been comparing their prices a lot and noticed that almost everything is 1-10 rmb more expensive at April's.

However, April's sale shelf sometimes has some good bargains. I picked up a brie and organic cheddar a while back for only 12 rmb and they recently sold an organic jiuce which was marked down from a staggering 80 rmb to 18 rmb. It's definitely worth it to keep your eyes on the bargain section, but go to Jenny's for non-sale items.
