Those selling from price.com.hk are mostly run in a back of house facility, like a warehouse, and with a minimal no. of staff, hence their price level is substantially lower than those retail chains. For bigger appliances like big screen tv, they don't keep stock. So when we place an order, they re-direct it to the distributor which will send it direct to us. If we buy it from a retailer, there is a slim chance that the retailer might cheat and send us a rejected or display product.
