I needed a way for my client to monitor their competitions pricing and be emailed when price changes were made on their website. I googled for “competition website monitor” and came up with several services. Some of them ( the ones that looked like they were still in business and making money and not in danger of shutting down overnight ) looked like they were targeted at online retailers and were priced accordingly. I found a solution that was only a couple bucks a month and met my needs. In my search I also googled for notify of changes to competitions website, monitor your competitions website, and femtoo alternative.
