The battery on my cordless phone hasn’t been lasting very long lately, so it is time for new one. I knew Best Buy had them but for some reason I looked around on the internet and found batteries.com. They sell the battery I need for $5 less than Best Buy ($9 vs $14) and there is free shipping. As I was registering with them and placing the order they asked where I had heard about them. Then I remembered that I think they were one of the AdSense advertisers on my iPod battery pack page. So I thought I should click through from there and get the battery. I’m glad I did because the advertisement had a code that gave me 10% off my purchase!
Geeky stuff: I wound up upgrading to the NiMH battery instead of the standard NiCad battery after seeing that it offered 1500 milliamp-hours instead of 700 for the NiCad, has no memory effect, and is better for the environment. However it cost me $17 instead of $9. I found a website that said it wouldn’t be a problem substituting NiMH and in fact it was recommended.
BTW: Last month my AdSense account racked up $3.42. My all-time revenue is $15.89. Not bad for nothing. See first entry.
