I think you're still missing the point.  The $267 isn't ebay fees - a lot of it is postage fees that are merely collected by ebay on Aust Post's behalf.

You'd have to be selling $1 and $2 items with $7.20 postage on them to be paying $267 in fees on $594 of sales.

I don't use ebay labels because I find they're much quicker to hand write than to fiddle around going through umpteen steps to print them.  I also don't have to worry about my old printer suddenly breaking down, or printing a bar code that won't scan properly when I get to the PO. 

I live in a small town and my PO only gets a pittance from AP for parcels that are pre-paid, but they get more if I pay when I lodge the parcel.  If it was cheaper to print ebay labels it'd be a different story but if it's no different I'll give the local PO the benefit of the extra money rather than ebay.  I don't know if ebay get a cut but it wouldn't surprise me one little bit.  Even a few cents would add up over a lot of transactions!
