Stuffin' letterboxes

Maud Up The Street is hopping mad - this week she found her letter box stuffed with advertising even though a "No Junk Mail" sign was clearly displayed.
What makes her even more annoyed is that of the 5 separate bits of bumpf lobbed at her by Woolworths, Aldi, The Reject Shop, Crazy Clarks and Cellarbrations - only one of these stores is in her local area. The rest are over 50 klms away.
