Heaven knows pastors love to read, and a price war between book retailers might just be a blessing to them. Walmart.com has dropped the price on their top 10 pre-order titles to $10, including free shipping. Also they are offering their top 200 books at discounts of 50% or more in a program called America’s Reading List. A day later, Amazon matched Wal-Mart’s pricing, and both sites have dropped those 10 promotional titles to just $9. It remains to be seen what this will do to already-beleaguered chain and independent book stores, but pastors might take advantage of the low pricing in the meantime.
