I have some sites in the health section and I work with many merchants across many affiliate networks.
One of those is Vitasprings from ShareaSale.

This merchant is voiding almost every sale I make with them. 95% of my reversals are from them. When I see a sale from them I almost expect it to be reversed the next day.

Please understand me, when you work years in a field with some 20 merchants and strange things almost always happen with one of them, IT IS A RED FLAG. The numbers don't lie.

I will remove all my links to them, I am fed-up already.
