no douible up's here, I spend ages waiting for stuff that never arrives
but if it was a small value item I wouldn't bother, being more expensive, I would have to ring them and get them to sort it out, the only time I ever came close to a double up was with a kids tent, the girls won one and then the same delivery guy came back with another told hiim NOT my name but my address but I had one, week later he was back
still not my name !!! back it goes, third time I told him to ring the company that sent it, I had one and it wasn't my name I didn't care what address they had on it, its wasn't mine..... I think he got the hint he didn't come back
