I wonder if you mind saying how much you spent at rakuten? I spent $185 and the fraud charge was 104.95. I wonder if the fraudulent charges are roughly the same as the amount of $$ spent and that is how they are gauging people's credit limits?
I'm also trying to figure out what other sites I use the same password for. I'm pretty good about mixing up my pw's but I do use that one for several retail sites.
I spent 170 on one card and 1349 on another.
