If you are a buyer, then you would be wise to keep quiet about this 😉 The very best bargains are those where "postage zealots" won't bid.

It shouldn't matter to a buyer what the postage split up is - if the decanter is worth $50, why not go for the one that has $30 postage where other buyers choose not to bid?

Consider - which is of these is cheapest:

$5 + $30 postage
OR
$30 + $10 postage
