expired $99 for 2 Year Skwirk Subscription - Interactive Schooling
This was posted 5 months 19 days ago, and might be an out-dated deal
It's usually $99 for 1 year but I received an email that it is now the price for 2 years for a limited time due to a new site release soon.
Skwirk teaches children between years K-10. They also allow kids to practice and receive points which can be exchanged for small prizes like these. (More a motivator than a site where you try and get back your subscription fees in prizes like an OB person would want. :D) (http://img402.imageshack.us/img402/3103/b86a8232403b46a1a17c...)
They have a referral system so if you buy the package make sure you post it in the comments below and when you refer 5 people you get another 12 months of access.
