Using paypal as a savings bank?

d`ya think this would be ok?
i dont have another bank and to be honest having the money lying around the house, would either lose it or spend it lol. i am sellign a few things on ebay which i am just keeping the money for them when they sell in my paypal anyway.

was just going to transfer money from my bank to my paypal account every week (including my £7...£1 per day)
wont be buying anything from ebay either as i am only on selling at the mo (trying to get space in here lol)

i think that would be ok but as long as you ain't tempted to blow it on ebay once you get a reasonable sum lol
