As a rule each participant will sell a minimum of 1 mini carry case during the campaign, so count on a minimum order of 1 large case for every 4 participants.
Example - If you have 300 participants:
300 participants will equal 300 carry cases
>there are 4 carry cases in a large case therefore 300 divided by 4 equals 75 large cases
>you will receive 1 in 20 free with your order, therefore for the above order you will order 72 cases and receive 3 free cases.
The above order is only providing each participant with 1 carry case, many participants will sell more then this.
The minimum profit on the above order would be: $10195.20
Again that profit is based on each participant only selling one carry case!
