Woot Bash Script

Here’s a SIMPLE bash script I cooked up for checking woot deals. It is has
been running for a whopping 5 hours (still no darned wootoff!) so you
might say it’s in very early Alpha. I set mine up in Ubuntu (which is
basically identitical to Debian for the purposes of this little
script.) I know there are fine folks out there that do this via
registration, but I really wanted keep my phone number OFF the Internet
(call me a paranoid freak–don’t worry…I will agree.)

I thought I might as well pass this on. Please, this comes with ABSOLUTELY no
warranties WHATSOEVER. Use at your own risk! Also, don’t criticize my
bash scripting, just make it better and post it or keep it to yourself.
Again, this is the product of a few minutes scripting (very basic but
works for me so far.)
