1) The problem → a customer start a free trial on stripe and then cancel it before 7 days. At the end of the 7 days they go again on our website and start again a free trial...How can I avoid having a same customer start again a free trial with the same email and or the same Credit card?
2) Why is this important → I don't want users to be able to sign up for the trial multiple times
3) What's your plan B → ?
4) Possible solutions we could build for you → A way to not allow users to re-purchase the trial
