Does it matter if I get the latest edition for studying? I'm thinking of getting materials that are (c) 2006, because they're cheaper.
I answered my own question. Based on amazon.com ratings I purchased the Kaplan GMAT 800, 2005-2006 and The Official Guide for GMAT Review, 11th Edition. Apparently there aren't many differences between these and the newest editions.
For a whopping total of $19.35 ($8 of which goes to shipping).
Hopes this helps another.
