Advertisers repaying for ad in second edition of book?

What did the contract specify?

Considering that contact information, locations or phones could have changed, I would definitely check to see if they want to be included in the new edition. Most businesses that advertise expect that a second go-around of, well, anything will cost more money.

Make sure you get feedback from the shops to find out whether they think the initial ad was worth the money. Do you have any metrics to share about sales and any way to track whether sales of the book corresponded to visits to the shops? If not, offer to make one. For example, people who buy the book are given a code to use for discounts at the shops, or a freebie item that the reader can get ONLY by visiting the shop. I once shopped at a store I'd never been to because a brand of lunchmeat I prefer was giving an insulated lunch cooler as a gift for new shoppers to the store.

Just a few thoughts.

Glen, I'd contact them if only to find out if ad placement in my book helped with sales. If it provided any kind of substantial bump, that's important to know.

If it didn't, that's good to know, too.
