So, I park in B&Q car park in prominence position, attach sign to roof, buy
packet of screws (therefore becoming a customer) and leave car there for 1
hour 55 mins. Remove sign, drive to Homebase & do the same. Then Morrisons
etc.

Perfectly legal, not flyposting, doesn't annoy people like windscreen
flyers, can't be banned for doing anything.

Result is that a HUGE number of people see my advert. Minimal cost, huge
bang for the buck.

Anyone see any snags? Any thoughts?

There is a big difference between those seeing and those actually
noticing it
