As many as i could fit in 2 checked bags + carry on.

I'm thinking roadtrip, but even with 2 people its still a 11 hour drive which will not result in great donuts.

(aim is to buy donuts at 1.50 each, and sell for 4 dollars each)

So 30 dollars profit per box.

Cheapest flight is 110 dollars, cheapest mileage earning flight is 180.

So if its air travel i need at least 4 boxes to cover airfare + then transport from home airport to distribution point.

Donut shop is in destination terminal so no costs on that side.
