In these high-tension economic times, it pays to be canny. That is, after all, why you're surfing this fine website in search of cost-effective gadgetry rather than traipsing up and down the high street.

This bright little thing comes with a coin slot (or indeed a note slot if you are that way endowed) and the lock is bestowed with its own unique combination. It also includes 5 labels varying from 'chocolate fund' to 'shoe fund', in case you need a reminder or some extra motivation for your savings.

And fear not, intrepid savers. Retrieval of said cash to spend on this website (or, should you be silly, somewhere else) is a mere bagatelle. No intestinal messing about is required. Simply unlock and remove for instant retail therapy.
