Buying Finasteride with Bitcoin help - UK

[Soundgrower]

I am in the UK and need to order Fincar from an offshore supplier I have used for years. They now request Bitcoin payment which is new to me. I have no idea how to buy it or anything about a virtual wallet. I just want to buy with Paypal or credit card but I find Bitcoin very confusing and insecure.

Basicly, can anyone in the UK advise where I can obtain finasteride or a generic type cheaply from a decent supplier that does not require Bitcoin payment ? If not, I need advice on where to buy Bitcoin and the type of wallet to obtain but it will be very reluctant.

Thanks
