For example, to send, say, 1, 4, 5, or 20 items, it usually costs me (rounding) $5, $5, $10, $10 to ship, which is the amount I'd like the buyer to pay.
If I charged $5 plus $1 for each additional item, then someone who buys 4 items pays $8 (which is $3 more than it costs to ship), someone who buys 5 pays $9 (which is $1 less than it costs to ship), and someone who buys 20 pays $24 (which is $14 more than it costs to ship). If I charged $5 plus 50 cents for each additional item, I would lose money if someone buys 6-10 items, and I don't really want any of those results.
I think it would be better all around to just charge exact postage (the packaging costs me nothing) but as far as I can tell this doesn't seem to be an option.
