When you UPGRADE you are GRANDFATHERED in at that price forever as long as you never let your SIX MONTH upgraded package expire for longer than 30 days. For example, if you buy Platinum your price will ALWAYS be $9.99 if as long as you never let your SIX MONTH upgraded package expire for longer than 30 days.
If everyone you sell a package to decides to upgrade again every six months this creates residual income for you. For example, if you make $4,000.00 in the first six months you should continue to make at least that much every six months as long as everyone continues to upgrade every six months.
IN ADDITION TO UPGRADING you can also buy your own CityPennysaver.com for the CITY of YOUR CHOICE for ONE ENTIRE YEAR, for only $10. (assuming it has not already been sold).
