USBC tested this concept to a small group last winter and the results allowed them to send the DVDs to a larger number of members.
The program involves a member receiving a free instructional DVD to preview. Then, they have the option to purchase and receive the next DVD in the series, which also includes several free game coupons for practice, send the DVD back, or keep the DVD as a gift. It allows bowlers who might not have access to coaching to receive great tips without any obligation.
