This outfit is a fraudulent advertiser. It advertises its software for $2.50 one year for the holidays but it charges your credit card for $32.05. I could not find a US vendor, just a Bulgarian address. I am not wasting more money calling that.
Its final charge is average for a small software but what is dishonest is the bait & switch…and since they are in Bulgaria the only way to protect your card is to cancel and get a new one, which is a wrong time of year for that…and I suspect that they anticipated that too.
DO NOT PURCHASE THIS AD BLOCKER online, it is a crock.
