Auctiva will you be offering the services that ebay is temporarily not going to have?
This part on question page is what I am really interested in.
USPS will discontinue Parcel Post service as of January 27, 2013. Active listings with Parcel Post will automatically be updated to the new comparable replacement service—Parcel Select®—which will be available in the selling flow and shipping calculator as of January 27.
Know that the new Parcel Select service will not be available for purchase through eBay Labels until March. Sellers that wish to utilize this service before it is available via eBay Labels—and sellers who have sold items with the Parcel Select service—will need to go to the Post Office or an alternate online postage provider (i.e. Pitney Bowes, Endicia.com, Stamps.com, etc.) to purchase this class of service. Also, be sure to upload tracking information within your stated handling time. If you would like to continue to take advantage of the convenience of eBay Labels until Parcel Select is added to the eBay Labels system, consider temporarily offering a similar service
Figured I would ask before deciding or investigating other options available.
