来自 Firefox 用户 14229227,6 年前I don't know and I don't care how this works, but I buy a lot of stuff on-line and this thing saves me money about 25% of the time I buy things. Today it was $30 off a $124 purchase. It does not get in the way and does not crowd your screen with offers. Used it about 6 months now and it is fantastic.
