I think the reason why sometimes you see bacon and eggs In the paper is because those are "stale" ads. If you advertise something useful like building materials, someone buys it right away, and you lose your advertised item, your ad is no longer in the paper. Of you advertise bacon and eggs, not many people are needing that item, you never sell it, and your advertised item stays In your shop, so your ad remains in the paper. Everyone gets a random 12 shops in their paper every five minutes or so, sometime you get lucky and get "fresh" ads, other times you get stale ads. Its to keep the game fair for both buyers and sellers. it would be difficult to find good items if everyone was competing for the same stuff. at the same time if you're selling and you don't have anything fantastic to sell people will still visit., That's why some rounds you score some loot and other times you don't. Sometimes I do a spring cleaning of my barn and silo and like to advertise bacon and eggs to keep people coming in.
