I wanted a specific pair of Vivobarefoot trainers in a specific size that was our of stock, but at the time the site didn't have an "Email me when this size becomes available" option.

I wrote a tiny Bash script called by cron that pinged the URL every hour, parsed the HTML and sent me an email when the text "<option>Size 45 - Out of stock</option>" wasn't there.

Not rocket science, but I enjoyed the fact that it was so simple.
