Abstract: A referral-based loyalty program incentivizes referrals by awarding rewards to primary customers for transactions by secondary customers. The secondary customers receive primary-account-identifying information, such as by hyperlink, and navigate to an order page of a merchant to establish an account and implement a transaction, for which the primary customer receives an reward. Primary and secondary accounts can be linked with one another at the merchant premises, or online, and can be associated with physical cards carried by the customers and presented during transactions. Rewards can be made contingent upon registration and activation of accounts.

Abstract: A portable toilet assembly has a twin-sheet thermoformed toilet tank, base, and urinal. The toilet tank has an upper thermoplastic sheet which is fused to a lower thermoplastic sheet. The toilet tank sheets are each coextruded from two thermoplastic materials of different colors, such that the toilet tank interior is a dark color and the exterior is a lighter color. Portions of the fused sheets extend outwardly from the tank and define flanges which can be used to attach the toilet tank to the toilet base and to the walls of a cabana. The toilet tank lower sheet has a downwardly extending pyramidal sump in which waste can accumulate. The base has a hole for receiving the toilet tank, a platform with downwardly extending sidewalls with outwardly extending ledges, and channels which extend through the sidewalls and ledges which allow flow of liquids from within the cabana and ventilation of noxious odors.
