Type of a scam Fake Invoice/Supplier Bill
There is a legitimate medical bill website at:
pay.instamed.com
If you accidentally leave out the first period (i.e. payinstamed.com) it takes you to a page that pretends to be a payment website with links labeled "Pay my Bill," "Pay Bill with Credit Card," etc. This is a blatant attempt to get people to accidentally send money to the wrong place.
