I understand their charging a flat rate; I understand their raising their rates because UPS has increased theirs,
BUT
$21 for shipping is insane, unless the final auction price is like $30 for a premium ball. I will be bidding on VERY few of their balls in the future.
That said, they have been very good in the past; they included $1 in refund when I was overcharged. Although they admit they cannot guarantee pin and top weights, they have met every ball I won on Ebay from them except one.
