lolol..
i think they thought that their distributor of bgvp would ship the dm6 to them quickly. and this failed. not very different than most shops (they accept orders, and then ask the distributors for stock). take in count that the sellers in ali don't get the cash till you confirm the package reception. the only thing they could win after a refund, is the difference ratio €/USD, if you bought using € (maybe 1-2% in the worst scenario? not that much); and number of orders increased, like you say, which is important (but many customers give a bad feedback when the item is not shipped, as a counterpart).
anyway, when they have stock they ship the items very fast (got a balanced cable and audbos p4 from them). so, if you are not in a hurry, it's a good deal.
first time i paid 177.75€ for dm6 (173.47€) and a bgvp balanced cable (33.05€, same or similar to stock one, but balanced; very well built, but a solder of left ground might be a bit off, +100mOhm respect the others), taking advantage of seller discount, seller coupon, and select coupons while they were available (28.77€ off, total).
got the cable, and now opened dispute for the dm6. no loss in ali refunds. i'll get 149.31€ (which is exactly what i really paid for it, proportionally). but it will take about 10-15 days, aprox.
now, pre-ordered dm6 for 136.89 USD (153.89 - 17 USD off by coupons, you only can use USD for these pre-orders). + 0.3% currency conversion + 0.2% immediate credit card top up fees. total, in euros, about 122€ at today's USD/€ ratio (27€ cheaper than the old order). but will depend of the ratio when making the big payment, on november 10-12th.
So what makes any of us think this won’t cotinue to happen during this 11.11 “pre order”? My bet is the intent of the pre order is for sellers to take orders (without inventory), with the hope that the sellers can somehow get inventory in their hands in time by November 11th (when buyers expect the sellers to start shipping their orders).
