Got free upgrade 15 years after original purchase

I bought a Mathemagics program in 2003 when my son was in grade 1.

I was really surprised to find the same company 15 years later who upgraded my program for my grandchild who is now in preschool. I am really impressed with the progress in program content and that they kept their promise for free upgrades. These people most certainly belong to the small minority group who promise and deliver. Good to know there are still companies out there who act in the interest of their customers. Thank you Mathemagics and keep up the good work
