I'm not saying this is reflective of all viewers/buyers of stuff from selly telly, however a few weeks back I watched a tv prog about hoarders. One of them was a woman and her house was stacked FULL of stuff. In one room, which she said was originally meant to be her craft room, there was TONS of craft stuff, most of it unopened. IW's sister channel C&C immediately came to mind. 'They make it so tempting' she said 'they encourage you to buy more than one and make it attractive price wise to do so ...'
Like I say, yes she'll be in a minority, however for those that do hoard, they're ideal customers for the selly telly vultures.
