eBay recently revealed that they are phasing out access to purchasing Parcel Select Ground shipping labels, even though USPS has made no changes in their services or policies, and it's offered by all other online postage sellers including PayPal, endicia, stamps.com, etc. You can purchase Parcel Select Ground postage through PayPal at
www.PayPal.com/shipnow
But do compare prices before you do that. For Zones 1 - 4, the USPS online price for Priority Mail is literally 10 cents more than Parcel Select Ground, and for Zones 5 - 8 the difference is less than a dollar. If you're a TRS you get a 3% discount when purchasing Priority labels through eBay, which makes it cheaper than Parcel Select.
IMHO Parcel Select ground should only be offered when necessary such as for hazmat or Oversize packages (i.e., length-plus-girth above the Priority limit of 108 inches).
On the label prep page, there should be an option to Edit the "Ship from/return to" address. This brings up a window where you can indicate whether they are different, and then if so you can enter an alternative "Ship from" address. I do not understand why eBay requires a full address rather than just the ZIP Code. Anyway, you could enter any address in the alternative ZIP Code, such as that of the Post Office you're mailing from.
