I’ve been noticing swap shelves in airport bookstores lately. Store owners are starting to encourage frequent fliers to leave a book and take a book. This helps you get fresh reading material for free (or cheap) and lightens your load of a book you’re done with.
A few airports, like Portland International, have used bookstores where someone has undoubtedly just sold back that bestseller you wanted, and you can pick it up for less than full price.
Alternatively, check out The Paradies Shops: they let you return a book you bought within 6 months and receive half your money back.
