They may have changed the contract rules as it may not have been very popular, i only have a few months left to run, but quite happy with the service
I did run the banner for about 6 months, but i have no way of knowing how many signed up from it, certainly did not receive anything from cardsave. When i e-mailed the boss, he said they had no response, so i pulled the banner, so he got 6 months advertising for nowt
