I may have missed the sarcasm in the previous commenter's post but I fail to see how the suggestion requires Paypal. Debit card + Standing order?

This type of thing has all kinds of uses, you can even use it on yourself. Is the hubby addicted to gadgets, and you both want to let him keep his gadgets, but keep to a budget? Easy, convince him to use a debit card that gets a certain amount every week, and if he makes tech purchases with anything but that card, you're going home to Mother.

You could even use for investing, especially if Paypal allows you to set a percentage rule rather than a set amount.
