I did before on 2010 and was (or were, not very good on english) a short amount of people. Pretty sure a lot of people did something on click and buy and sure some people will get some problem, nothing is 100 % sure. Maybe 1% of people that do something on C&B get some problem, or maybe is something like this. One guy get a problem with that page and start to move the ball saying it's a shitty page and ppl stay to believe what he told.

Wait some time and let's see if it work or not. How can you say it's a shitty payment system if never had a problem with it?
