Yes, of course. Don't forget you have a Customer Loyalty Discount based on the number of courses you've already purchased. Plus, any MS Office classes you purchased after November of 2007 qualify for a FREE upgrade to the new versions, when released. For any older classes, everyone who has them will get a special email from me with a discounted price when they're released... so if you bought Excel 101 back in 2005, as soon as I released Excel 101 for Office 2007 you'll get a discount notice in email.
