When you do your 2013 shopping for athletic gear, diet books or whatever else you need to achieve your New Year’s resolutions through this Amazon link (or the one on the lower right side of this page) you support this blog at no cost to yourself. It’s much appreciated!
UPDATE: Since the move to WordPress dot com in December, 2014, this has gone away. They don’t allow users to sell anything except what they’ve made themselves, and then only by linking to somewhere else. But the advantages of WP outweigh the disadvantage. Its sites are harder to hack and besides I never made a penny off the Amazon deal.
