However, USPS is less expensive for most packages less than 15 pounds. Larger items will be quoted individually. There is no fee for clothing items or those items which do not require packing material. I regret having to impose fees however, bubblewrap and packing peanuts are surprisingly expensive. In addition there will be an additional fee for large boxes which must be purchased.
Insurance is optional, but the buyer assumes responsibility for non-insured items.
Post office insurance does not cover theft from your mailbox after delivery. So if your item is not fragile you probably do not need insurance. I take great care in packaging. In 2.5 years, I posted 1200 items and never had a single problem. I then used a post office which I generally try to avoid and had four incidents of breakage in one shipment.
