Today's side deal combines the advanced algorithms of a Golden Tee machine with the scientific mechanics of swinging clubs at night. For $65, you get one custom driver fitting at TaylorMade Performance Labs, located at The International Golf Resort in Bolton, a $150 value (for non-members and non-hotel guests). Groupon buyers also get a $25 credit toward any purchase. Bring your own driver for a scientific analysis.

Unlike a tuxedo fitting, getting fitted for a custom driver provides valuable feedback that pertains to more than how smooth your hips are. TaylorMade's physics-friendly experts place reflective markers on key points of your body, then capture your swing across nine high-speed cameras to reproduce a 3-D animation to take home on CD. In around an hour, you'll know more about your golf club than most married couples know about each other's font preferences; you'll receive statistics for over 25 aspects of your swing including launch angle, wrist-cocking angle, and the computed distance of carry and roll.

After the science storm calms, the TaylorMade factory will ship you a fine-tuned club to meet the specifications of length, lie, loft, shaft, and grip as determined by your session. In about two days' time, your noble driver will be ready for its first tour of duty.
