I live in an area of Devon that was constantly bombarded with takeaway menus, up to 8 a day on occasions. You could watch canvassers following each other down our road posting various menu's for fast food. I browsed the internet and came across www.no-junk-mail.co.uk  selling no junk mail letterbox sticker that stop up to 90% of posted junk mail in the UK, including these dreaded takeaway menus. I purchased one for £1.49  and received it within days, I simply stuck it on my letterbox and the junk mail stopped. I haven't had a takeaway menu for months now. I could no believe how much these stickers could stop junk mail, but they do. Well worth a look in the link above.
