Because usually you could expect free registered shipping at that price, but not from MF. Well, to be fair, you cant really expect anything from MF. :D
Manafont starts the “more $20 oder registered shipping” a few days ago. I think every HongKong Shop has sometimes problems to solve the problems of the customers. I buy a lot in the HongKong Shops and if a problem come up, most are solved well, but some not (every shop fails: DinoDirect, Manafont, Dealextreme, Kaidomain).
I would prefer Manafont, because most orders were delivered well and I don’t want to spread my address to all shop of Hong Kong.
