In the initial link, the price appears to have increased to $39.99 with free shipping. The second link cost me $25 after shipping, so I hit that. Can't beat $.50/ft. Thanks for the heads up!
Yep, sure looks like the first guy bumped the price. He probably saw a sudden increase in interest in his item. He isn't sure why, but he knows someone is interested in his product and he's gonna charge for that interest. LOL
