I read Instaflex reviews - Amazon,here and instaflex site.I agree with some reviewers-everyone "authorised" Instaflex to deduct monthly card payments.
Funniest question - "how did they get my card #?" You gave it to ship product! However I would be pissed if it happened to me. There is no free lunch -i read conditions when offered free product. It's common practice-like book clubs sending monthly book unless you cancel.
I hate these auto deals - don't even give address unless i know I'll buy.BTW, many Amazon reviwers said takes 2 months to work -not 14 days
