JMO as a buyer but $7 postage for a THICK book (weighing less than 500gm) posted in a satchel is fine BUT are any of your books thin enough to be posted as large letters ie less than 2cm thick ? You could post them for a few dollars if they are.

Also,what a shame you didn't phone ebay when you copped that neg last year.As it was a pickup item,I wonder if you could've argued about getting it removed.Too late now unfortunately.
