What do you mean by "the coupler conversion kits?" Bachmann doesn't make
any. The Spectrum line uses knuckle couplers compatible with Kadees and
all similar couplers. Do you want to replace these? What with?
As for minimum shipping and handling on international shipments: there's
additional paperwork involved, which means there's additional time
involved. (Even a private mailing costs extra time: you have to fill out
a form when sending a package overseas, no matter how small.) There's
also (usually) additional packing materials required. If they ship by
courier, the courier charges a fee for handling whatever customs
paperwork must be done. Either the supplier eats that, or you do. Fact
is, the minimum S&H charge just barely covers their costs.
