Consider registering to receive free samples as a way to save money. It may not seem like much, but I bet if you add all of those free samples together, you'll find huge savings.
Here is a link to a Free Sample of Purex http://www.freesamplepurex.com/.
When you stay in hotels, save those free samples as well. If you are staying for more than one night, place the unused samples in your bag and housekeeping will replace them each morning....more free samples!
Just an update for you, as of today, October 9th, 2012, the free sample of Purex is still available while supplies last. So be sure to check out the link above and get your free sample.
