I have been doing these, and I always send to Zone 5. The first time I did one and the price was exorbitant, I wondered if I would receive full reimbursement. I did. So I keep doing them, always to Zone 5. I use a credit card that gives me 5% back, so the more they charge, me the happier I am! They actually should not accept the shipments, but about 50% do. Otherwise, I buy overpriced boxes, or tape, or something else that amounts to about $10. I have always been reimbursed.
