Day 15 of My Money Challenge, a Link, and an Update

First for my money challenge:

• I did another survey for Opinion Outpost which showed up in my email.  I haven't yet figured out how it works but it looks like the survey that I did that took about 5 minutes will pay me $2.
• We gave our idea of being Las Vegas hosts a whirl today, picked up a friend from the airport, and he insisted on paying for our lunch so we got a $15 lunch for free!  We may turn this into a business!

And a link:

• I came across this post on reddit and it looks like a lot of useful tips for saving money.

And an update:

• Yes we caved to peer pressure (or sister pressure) and we will be going to the SIL's wedding the first weekend of December.  I have been checking airline ticket prices and what started out at $750 for two tickets this weekend, went down to $650 this morning, then when I checked prices again this evening it was $555 for two round trip tickets so we quickly bought them.  We will also be riding to and from the airport with the guilt-inducing sister who is renting a car so that is another expense we won't need to pay, plus lodging is free as well (I'm kind of curious to see the place that they rented--it sleeps 25 people!).
