That's an odd statement to make.

Now we even pay ten percent on postage despite being unable to charge excessive postage.

I know you didn't mean it that way.  It's difficult to compete against the big sellers.  As a some times seller ebay is much cheaper for me to list on now.  Free to list and the final value fee is reasonable and the world wide advertising is great.  Paypal is the icing on the cake because now I don't even have to keep checking my bank account to see if I have been paid.  Love that so much 🙂
