Pristine Health review: unauthorised charge to credit card

like others on this site, I thought I was just paying for postage and packing, but instead my credit card has been charged $87.62.
My credit card company have been very vigilant and brought it to my attention and advised me to call their Charge back department (that will be done tomorrow)
I didn't even see any clauses which required me to opt out of whatever it is they think they're charging for.

In agreement with others, I think this behaviour is disgraceful and the company should be closed down.
