So I ship all my items via USPS 1st Class Package/Thick Envelope service (13oz or less). I print out my postage online, and then I put all my packages in a USPS drop box at the end of the day. This method has worked well for me, but as sales have began to increase, this method has become a little bit impractical. There's got to be a better way to do this than driving to the Post Office and shoving 100+ packages in the drop box at once. Does anyone else ship large volumes with this service? If so, how do you handle it? I know you can schedule pick up with USPS, but according to their website, pick up is only available if you have at least one Priority or Express Mail package.
