do you bulk buy stuff when there's a good offer on?
shower gel - only ever buy it on offer. not bothered about brand...as long as its a quid, I'll have it
bulk buying - body shop had a very good online deal recently, so bought 6 x maca root deodorant and 3 lots of night cream. net saving - bout half price.
similarly, super drug had sensodyne repair and protect toothpaste at better than half price. bought ten of the fuckers. why not.
so yeah...stuff like that.
