Initially they will have to send it to another RFD, which will cost you probably £25 for them to handle it on top of the postage, however after that they can return it direct to your home address but the post will be £20-£25 each way & is almost certainly NOT included as free.
So £50 on top of the actual cost to start, plus £50 for each "free" service.
Remember in the first 12 months there will be a manufacturers warranty anyway if it goes wrong.
