The chip below is currently at $12.50. Ebay's final value fee would be $1.50 and then PayPal gets $.75 for a total of $2.25 in handling fees. That leaves 75¢ for shipping. On each additional item you save 50¢ leaving 25¢ for shipping. So I'm charging 75¢ shipping on the 1st item and 25¢ for each additional item in this example.

I don't see too many people buying multiple chips, but if they buy a large number of cheap chips then the ebay and PayPal fees would be less. Conversely, if a single chip sells for $100 I don't plan on asking for more to cover the handling fees. I think it'll all balance out in the end.

But for you, Jim, I'll charge you $1 over the handling fees on your total order.
