USPS Priority Mail or Parcel Select?

When I initially started this business, I would do all my listing defaulting to USPS Priority Shipping for packages over 1lb and offer USPS Parcel Select Ground as an option at checkout. One of the main reasons was that the Priority mail was discounted and the discount would help offset the eBay fees. While it is a little faster, it often is maybe a day more typically, so the reality is the timing is not that important if you get it out the door in a timely manner. It is important to note that the Priority does come with $100 of included insurance, however, the claim process is so painful and it has never yielded a positive result and thus it has no value to me. So I don’t do claims and just refund and treat it as a cost of business. Now I list most everything as Parcel Select by default that would have been Priority. It allows my items to have a lower overall price and has helped increase sales, albeit not by that much. The downside is that it is not insured and that there is no eBay
