stockcharts.com have a promotion to upgrade basic member to extra for $1 per month.
For example, if I get 13 month of basic membership for $154.95.
Then I can upgrade my account to Extra! with $13
Once upgraded, I can downgrade from Extra! to basic and gain additional 9 months of Basic membership.
That means it is $167.95 for 22 months...

The promotion ends today at midnight.
