Convenience yes, price no.
"Undoubtedly a very efficient and easy to use service - recommended for these attributes.This does of course come at a price, the price paid for your goods. Moral of the story is to never accept the first offer, with a polite refusal yielding me an extra 50 quid ! Although I am sure they will deny it, I have a sneaking suspicion that they deliberately offer low initially, on the basis that a certain percentage of customers will accept the first offer. Good business if you can get it. Go ahead for the convenience, but be prepared for the offer.....Yes i am aware thank you that if i recommend a friend I can earn more !"
