If you’re looking for normal supermarket stuff I don’t have an answer for you, but little shops that sell snacks drinks etc will usually deliver if you live nearby – can find one near your place and ask.
One thing I just checked out that waifood site, in English, and saw some oddities:
(Best By April 5th)Whipping Cream
(expired) Dole Tomato Juice
Woot, can’t wait to order me some expired tomato juice.
just curious why you would want that. Is Chengdu so spread out and inaccessible that you would need groceries delivered? Or are you just some really rich guy who can’t be bothered to go to the grocery store?
I’ve used waifood and I think they are decent. (Expensive? What were you shopping for?) The last time I sent in an order at 11:00 at night,chose COD, and they were at my door at noon the next day. They answered the questions I had about the products in English as well. waifood used to have a klunky website and minimum Y300 for free delivery, which was just ridiculous, but now the website is much more user friendly and the free delivery starts at Y50.
I also use taobao (in Chinese) for perishables, search for local suppliers and then go to the places directly to see their wares/storage conditions before getting stuff. One place I trust is http://xiaoshui.taobao.com/, where I buy things like chocolate, butter, cream, dried cranberries, vanilla beans, and MG mozzarella which I really prefer to that Anchor brand everyone else seems to have. Their free delivery starts at Y99.
