Have an expensive genealogy book on your wish list? The promo code HOLIDAY30 gets you 30% off any book at Amazon. (Readers outside the U.S.: I assume this works for you too.)

The promotion, however, only covers physical books. The discount does not apply to audiobooks and Kindle e-books that customers may want to purchase. The discount expires tonight at 11:59 pm Pacific (December 1, 2015 at 02:59am Eastern).

This is undoubtedly the best offer that book lovers can get from Amazon during the holiday season, so it would be a waste not to use it. However, choose the book for your discount carefully, as the code can only be used once for every Amazon account. Other conditions: The discount only applies to physical books sold and shipped by Amazon.com. The maximum benefit you may receive from this offer is $10.

A 30% off any book at Amazon is a pretty significant one though, especially for genealogists that have been thinking about purchasing a reference work, , a hard-cover coffee book and the like. Time to buy yourself a book! And now I must consult my own wish list.

Tomorrow we’ll talk about the antidote to all this shopping: Giving Tuesday and Genealogists for Families.
