Due to shipping services' poor quality (and I mean ALL of them) I will be sending all breakables double boxed and double padded. This makes for slight increases in postal fees but double costs for me on supplies and time. I don't like it but there will be an added handling charge. Usually just $3 (which works out to less than $10/hour).
As I deal in vintage and antiques, insurance $$ cannot ever replace the value to my buyers.
