You can set an incentive for your team to give them another reason to push their business up to the top. Products need to be sent and are unique to only certain people. Services and/or outings are also unique to certain people and are only good for people close to your area. My suggestion is to pay-it-forward in money as the incentive. This can be done internationally and "everyone" likes money!
My team incentive is: I will donate 35% of my profits to the "member" in my team that has the highest enrolled members between May01/18 to Aug31/18 - Paid directly into their wallet on Sep01/18
