Anointed Meat

I just heard this on the radio today, and thought it was pretty innovative: Charles Spurgeon used to have transcriptions of his sermons printed on butcher paper, and then he paid the local butcher to wrap meat purchases with the paper. That way anyone who bought some meat also got that week's sermon. Considering my receipt at Cub Foods today was about 4 feet long (not an exaggeration), perhaps that's the next medium for evangelism. They already put coupons on those things. I can see it now: go grocery shopping and get last week's sermon on your receipt!
