When you say send their products to, do you mean you’re having it shipped to you? Can you just put in a family member’s address or another friend that your friend doesn’t know?

Not sure the type of business, but maybe send to a family members address (like your parents or similar) and then you can pick them up later and send to a local charity that might benefit? (Depends on the items I suppose).

I do that sometimes- buy something from a friend’s shop, then give as a gift to someone else. Win-win
