Most of my packages cost $4.24 - $4.41 to ship out using USPS Ground
Advantage, but the buyer usually pays only $2.50 for shipping. So we add
$1.74 or so to this of our own funds that the buyer hasn't covered when
we purchase the shipping label. Rare...
Thank you so much, I don't know why I missed the fact some of them were
set as a flat amount. I appreciate you looking into that for me, I have
fixed the issue now.
