Hi phun-staff,
I'd recommend investigating whether you can get home pick-up on a daily basis for your packages. I've listed some options below.
I recognize that these options might not be ideal for every seller and every situation, but hopefully they will help you and others on this thread.
Free carrier pickup is available from USPS. After you have printed your label, simply request a pickup from USPS. USPS free carrier pickup can only be used if you are shipping at least one Priority Mail or Express Mail package domestic and international.
For UPS shipments, once you have printed your label, you can drop off your packages at any one of nearly 4,400 locations of The UPS Store. You may also hand your package to a UPS driver at no additional charge. Or, for an additional fee, arrange for a pickup through http://www.ups.com/ or 1.800.PICK.UPS. You and your buyer can then track the package right in My eBay, since UPS provides tracking from initial scan through delivery.
For FedEx® shipments you can take advantage of the FedEx Convenience Network which offers more than 50,000 convenient drop-off locations where you can drop off your shipments. Find the location that is most convenient for you or schedule a pickup at fedex.com.
