One last comment on this issue. USPS priority is tracked and works well. Insurance costs extra but very little. About the only advantage UPS has is the insurance that is included up to $250 I believe. But It is a pain to file a claim and if you file a few claims they start inspecting your packages and treating you different. I ship hundreds of items USPS flat rate priority and have not had a single lost or late item, always delivered in three days. I have had a couple of damaged items and I ate the cost of those but two out of a hundred is not bad.
