Yes as Suneet said the difference comes from covering the following costs:
1) Shipping from manufacturer to me
2) PayPal fees (3.5%) for processing the orders
3) Packing materials that I have to purchase to individually package each frame
4) Shipping from me to you for the individual frame(s).
5) My time for doing all the above (probably works out to 5 cents per hour.
If you have a way of doing it for less let me know.
