Pizza Hut is tying its October promotions to a book-sharing giveaway, a feel-good move for families and a cheap bit of brand marketing for the chain.

• Pizza Hut is working with Little Free Library to put up small neighborhood book exchanges shaped like its red-roof restaurants.
• Each box comes stocked with books plus Pizza Hut giveaways.
• National Pizza Month has run every October since 1984, and chains use it to push deals.
• Stores are promoting their usual lineup — original pan, thin crust, stuffed crust — with local deals through the month.

Outlook: Expect more pizza chain promotions and tie-ins through the rest of October, heading into Halloween.
