Where to find that mysterious setting to allow people to buy from you without them needing to create a PayPal account. It is one of those things that drives me a little crazy as I can never remember of the top of my head where to change the setting. So for my benefit as much as yours I have laid it out below with screenshots and links to speed up the process.
By default it’s turned off would you believe so every single PayPal user needs to make this change in the setup stage.
Very handy reference manual for PayPal Standard, it has lots of screenshots and even though a few years old still valid as PayPal has not changed most of their screens for years:
