Surprise membership fee
It is a terrible model for a company to spring a €40 "membership fee" at checkout. Really?! Along with a supposed, buy a pack and save message. I just went back on the site from the beginning to make sure that I didn't miss this message along the way, but no, they seriously waste your time looking through teacher profiles with a posted rate to then tack a fee at checkout. It's annoying and dishonest. I would have considered a membership fee, but as a moral stance, now I can't sign up.
