*Can* we sue? My understanding was that if they sold
us copies and
then tried to restrict redistribution of those PD works (and no EULA
or contract was signed) simply through copyright mechanisms, then we'd
have some sort of legal recourse, but that we can't demand that they
make the works physically available simply because they happen to be
PD if they decline to have us as customers.

IANAL so don't trust me, but i don't think someone could force me to pay
for a PD material. However they would probably ask you a fee for sending
you it or having saved it for X years :-(
Lawyers should be consulted.
