Theres no legal padded envelopes, just regular. Insurance and tracking is free, no extra cost. Also, if you pack everything right there is no need for insurance. In 13 years of shipping I only had about 4 things that got lost or damaged. A needless expense. Regional rates are great but the boxes are skimpy, just make sure you protect fragile things right. Remember tape for a shipper is cheap just like nails for a carpenter, use it.
