So..... he blindly gave money to his supplier without getting the stock?

Don't this work the other way around, supplier usually will give out the stock and wait for payment end of the month? Why is he paying money for then? Promises?

So because you offer lower price, you have the right to hold on to a customer's money for a longer period?

Yes, I understand different suppliers have different T&C. I'm also a part time dealer as well, thats why I don't really understand why would you willingly pay an amount of money to a supplier without the guarantee of stocks?

I've seen suppliers who three storey buildings close shop in an instance because the owner decided to run away, leaving everyone at a loss. I wish you the best of luck in getting the supply, because if the person is buying 11 sticks, it's meant for his customers / market and not for his own use so time is a critical factor to him as well.
