Well, "glitch" may be an overstatement, but thank the area's introduction of a new Ecommerce Web site for people to buy passes online. Some technical difficulties related to the Web site have led Wachusett to extend the deadline for its GPS season pass deals by two weeks. Groups of four or more skiers can form a Greatest Possible Savings Club and buy the area's three types of Century Passes at discount prices until Oct. 29. The Gold Century Pass costs $479, and is good for unrestricted skiing all season long. The GPS Silver Century Pass costs $259, and is good for skiing all nights, non-holiday weekdays, and weekends before Dec. 24 and after Feb. 28. The GPS Bronze Century Pass costs $199, and is good for skiing non-holiday weekdays and all nights.
