I was going to say OP's (your) girlfriend went through this 8 months ago, which probably meant a completely different looking checkout page. We all know startups are constantly trying different things in their UI to increase conversion.
Still a scam. OP's girlfriend (and probably many others) didn't know about this deal and didn't (knowingly) consent to it.
