I was a member of swapgame and i found their customer service poor and it sometimes took them 2 days to send out a game after they get it back. I am now a member of boomerangrentals.co.uk and i find them very good with great customer service and have good prices, they offer Unlimited Priority so you have first choice on new releases and have the cheapest value package. they give you a 21 day trial I cant say much about gameflirt as im not a member I would go with boomerang but its your choice, hope this has helped.
