Want to know how to purchase HeartGuard for as low as $5.99?
It's something we all have to buy for our furbabies -- might as well save some money doing it, at least once!  ; )

1-- Go to TreasureTrooper.com and join.  TreasureTrooper pays you to
          complete offers and visit websites.  I would use an e-mail account you
          have set aside for spam, such as a Yahoo or Hotmail free account.

2-- Click on Cash Offers and scroll down until you come to the PetCareRX
          offer.  Click on the link and make a purchase of HeartGuard.  They
          have it available for as low as $20.99.  You're going to buy it anyway...

3-- Go back to TreasureTrooper.com and click on the Done button next to
          the PetCareRX offer.  Once your completion of their offer is verified,
          TreasureTrooper will put $15.00 into your account which will be paid to
          you the following month either via your PayPal account or by check. 
          Voila - you've purchased HeartGuard for as little as $5.99, depending
          on which HeartGuard you use.
