According to BBC, retailers are warning that they may not be able to fulfil Black Friday orders due to stock shortage especially in technology area!. 1. Why have a sale when you have insufficient stock ? Genuine sales are where a retailer is getting rid of excess or slow moving stock or those that are about to be superseded by newer models. 2. How are they so sure they can’t supply orders if they don’t yet know the level of demand? looks to me they are putting out scare stories just to drum up business, or perhaps to counter recent stories in the papers that most Black Friday offers are not that great a buy .
