You can encourage your downline members to purchase from TripleClicks only with your personal example.
This is just my personal opinion.
So,show them with the personal example that the benefits exist when purchased at TripleClicks, as far as getting the VP, as MRP, how fast progressing at SFI if you buy something through TripleClicks etc. If you yourself do not buy anything then you are not worth any 'persuasion' that others do.
