It was the only reason I went to Compubank, but I'll probably stay for the service. It's the drug dealer mentality that all banks have (use to work for a bank), give them something for free (say ATM transactions), get them hooked on them, then either take them away or start charging for them (ATM transactions) and the people will stay with it.
By the way, everybody should also reply to the e-mail urging them to stay with clickrewards, it may do nothing, or they may see how many people were actually interested in them.
