Former Pentagon chief and Marine Corps general Jim Mattis’ upcoming book about the lessons he has learned during his lifetime of service has been suddenly discounted the day before its Tuesday release.

At BJ’s Wholesale Club, a bulk discount household store, in Falls Church, Virginia, the hardback edition of his book, Call Sign Chaos: Learning to Lead, was already on sale Monday at $15.79 — a 43% discount on its full price of $28. On Amazon, pre-ordered copies were available at $18.77, a 32% cut.
