Let us start with the price of a small ship, $15 for easy figuring.
Assuming a 50% markup, the retailer would be paying $10 for the small ship. Since places can sell it for less and make money, such as MM at $10, ($9.99 rounded again), they obviously dont pay that much!
Assuming a 33% markup, $7.50 would fit as that also fits for places like MM, as they would be making $2.50 per ship which is 33% of $7.50. (Which also fits a retail price of $15 after a 100% markup!)
With a 50% markup, they would be paying $6.66 and with a 100% markup, MM's cost would be $5 per small ship.
With these assumptions in place, FFG is probably charging their distributors somewhere between, $5 and $7.50 per ship!
So looking at the numbers, and thinking of normal manufacturing cost to retail prices I am willing to put FFG's cost of manufacturing a small ship between $2.50 and $3.50!!
So what is my point!?! FFG is making money on XWing by selling LOTS of ships! They make a little money on one ship, the distributors make a little more and the retailers make some more!! But no single entity is making a ton of money on that $10 or $15 ship! It is spread out!
I think they have the pricing set to what the market can bear while keeping the number of units sold at a maximum! Its basic economics!
