Whilst reading the Plymouth Herald yesterday, our local daily paper, a Plymouth window cleaning company have put an ad in it allowing readers to save tokens and receive a free clean; a bit like the Sun's readers holidays I guess.
Now, having thought about it for a while I reckon they've been quite clever.
Okay, the herald covers a lot of areas in Plymouth so the cleaning requests may come from a wide area, and they may end up cleaning for free for longer than they'd hoped, but they could well end up securing a lot of extra, regular customers for when the offer ends.
To be honest I wished I'd thought of it - perhaps it'll work for carpet cleaning
