Never have. Problem is that the proviso usually is, that both items have to be exactly the same and, if I used this 'offer'!*** I would be buying one for my mum and wouldn't want us both to have the same thing, whether it be jewellery or perfume. If both items are going to the same address, I cannot see why there is a problem with ordering two different variations, under the same item number. Actually, why not adopt the same policy as gems tv, and have one flat postage rate for all orders placed in one day, whatever the item number?
