I just got a 500RMB discount on a speaker from jd.com for 11.11. It was originally over priced , but I still got it for a couple of hundred less than I could on taobao.
Look for the line which says, 服务：由 京东…. located under the delivery district / stock level for items sold directly by JD. You can also use the 京东配送 tick box when searching.
Items bought directly from JD are usually delivered in the afternoon if purchased before 11am, and in the evening if purchased before 3pm. I specified evening delivery to home. I’m not holding my breath though given how busy they will be.
