Amazon has put the large print edition on it's 4 for the price of 3 list. This is not the 8x10.5 size, but the more compact 7.4x9.4 size. I can never remember the exact dimensions.
Still, the book lists at $9.95 (less than the $12.56 for the larger trim size with fewer pages), so plunk it in your shopping cart along with three other books also in the 4 for 3 list and you get the lowest price book for free. The $25 free shipping still applies.
How can you beat a deal like that?
