Have you noticed how when you're out shopping, some items just seem to be going up all the time? This is one of those items, for the very simple reason that it's an inflatable bath pillow and frankly if it didn't go up, it would actually be pretty useless. In fact, it would just lie there, all flat and lifeless, like an unlucky hedgehog that has been run over by an articulated lorry. So the trick here is to put your mouth around the nozzle and blow till it's as full of hot air as a finance minister trying to convince us that the economy really couldn't be in any better possible shape. In case you're wondering , when deflation occurs, the pillow goes down, not the price.
