As a marketplace how does the discounting work? Do they entice their merchants to put up discounts on this day? Are they mainly doing centeralised fulfillment like a fulfilled by amazon or is it up to the merchants to dispatch?
taobao.com is like ebay, tmall.com is another branch, with certificated salers. There's no fulfillment like Amazon, everything is up to the buyer to choose.
The discounting began a month before Nov 11 where the price of the item is set as the ceiling, from the then price can only be made lower.
