This might be too late for this season to help people out but one of the best things we’ve started doing is signing up for click and ship through the USPS. Located here: https://www.usps.com/ship/print-a-label.htm
You need to create an account and you can save addresses so make shipping easier, but you don’t have to. You can select what type of packing you will use either your own or the standard priority mail boxes or envelope. There are discounts for printing your own label and you can choose additional options like more insurance and notifications. Pay on line and print your label, pack it up and you can just bring it to the post office and leave on the counter. No waiting in line.Do yourself a favor, it is worth it!
