I know for me it is 10% - since I am low volume. But I am curious what it is for high volume sellers as when I compare their prices on
ebay to their prices on the same coins on their "own" websites they aren't as far apart as I'd expect.
I'm also liking that more sellers are listing a "by check" price 3% less than the cc one right on the price page. Makes it easier and less of a haggle now.
