Not a good idea mates. Two is normally the most one wants to enter a partnership with. Each then only has one risk partner.
Each partner entered in adds more risk. So six partners would give each person 5 risk partners.
Either of you could be sued by 5 different people, robbed by 5 different people or shorted by five different people.
Let's say the delivery is stopped by customs. One of the parties didn't want that particular order because it was high risk. SO he sues the group.
One guy is late to the delivery pick-up and thinks the others cherry picked the lot.
One guy shows up early and steals some product.
I know this is negative but unless very tight agreements are made by signature and verification, one can get into a lot of trouble.
