Abstract: A business promotion system and method which encourages customers to visit a business together to redeem a promotion. The business promotion system and method generally includes a system and method which encourages users to share first-tier promotions with a minimum number of recipient users via a plurality of user devices to unlock a virtual badge and a second-tier promotion. Badged users who have earned a virtual badge may visit the business individually to redeem the second-tier promotion or may unlock a third-tier promotion by visiting the business with other badged users displaying a virtual badge on their badged user devices. In such a manner, customers may be encouraged not only to share promotions with other potential customers, but also to visit the business as a group to receive greater discounts and/or other incentives.

Abstract: An apparatus for securing a first joint member to a second joint member in a universal-joint comprising at least one pin for insertion along a Y axis, at least one pin for insertion along an X axis, a coupler between the joint members configured to receive these pins, and a security pin configured to traverse the coupler along a Z axis when each of these pins are within the coupler, such that the security pin penetrates at least a partial hole in each of these pins. The at least one pin for insertion along the Y axis may be a main pin having two recesses. The at least one pin for insertion along the X axis may be two bracket pins each having a bracket extension. Grease may be injected into a center of a joint member through a fitting. Retaining rings may shrink the boot to a pre-defined limit.
