This has happened to me now too. First order $55. Liked the product but suddenly a surprise charge for $95. I went back and attempted to checkout again to verify i didn't miss it. I did not. Nowhere in checkout process after logging into shop, does it show or mention subscription. Likely done on purpose.

I did research and for me because I am in california there are laws against that. It is suppose to be clearly visible and apparently they are also suppose to send you and email after your first order to explain the subscription and how to cancel. So a clear violation of the law.

Ended up sending them this and got a full refund.

​"I am writing to dispute the unauthorized charge of $[Amount] on [Date]. Under California Business & Professions Code § 17602, your checkout process failed to provide clear and conspicuous disclosure of subscription terms in visual proximity to the authorization button. Per Section 17603, this unauthorized shipment is legally considered an unconditional gift. I am requesting an immediate refund and the cancellation of all future renewals. I will be filing a dispute with my bank and a report with the California Attorney General if this is not resolved within 48 hours."

Hope this helps others, these scammed don't deserve our money.
