You don't need Paypal as Missionfish take care of all that.
All you need to do is fax them a paying-in slip with your branches bank account details on and they set it up themselves. As you can see, as a branch we're spanking new to all this so I can't really say how successful it will be. £22 for a pair of mice is awesome, though.
But if you do a bit of research, you soon realise some CP branches and other charities are doing really well out of Ebay.
Ideally, we'd love a support shop but we don't have the required capital behind us. Barmy ruling, that, if you ask me!
