The link also includes stuff on FOB and CYI that any ebay'er ought to read.

that of the buyer is to accept and pay in accordance with the

the parties "unless otherwise agreed," the agreement may not only
shift the allocation but may also divide the risk or burden.
2308. Unless otherwise agreed
(a) The place for delivery of goods is the seller's place of
business or if he has none his residence; but
(b) In a contract for sale of identified goods which to the

place, that place is the place for their delivery; and
(c) Documents of title may be delivered through customary banking
channels.
2310. Unless otherwise agreed
(a) Payment is due at the time and place at which the buyer is to

delivery; and
(b) If the seller is authorized to send the goods he may ship them
under reservation, and may tender the documents of title, but the
buyer may inspect the goods after their arrival before payment is due
unless such inspection is inconsistent with the terms of the
contract (Section 2513); and
(c) If delivery is authorized and made by way of documents of
title otherwise than by subdivision (b) then payment is due at the
time and place at which the buyer is to receive the documents

on credit the credit period runs from the time of shipment but
postdating the invoice or delaying its dispatch will correspondingly
delay the starting of the credit period.
