I used them a fortnight ago for an AEG oven and warming drawer. No problems at all with them, plus 2% cashback on topcashback, which tracked almost immediately (on the pre-VAT amount). Delivery arrangements are excellent - you get a call and text the night before with a 2 hour slot, then a confirmation of the slot from the actual driver on the day. Very impressed.
I needed the oven delivered asap, so paid a tenner for a Saturday delivery (ordered on a Thursday afternoon). The other item was out of stock, and that got free delivery the following Thursday.
