I just want to note that the planned increase will affect shipping costs in 42.7% of US zip codes. Perhaps these zip codes don't get a lot of mail, but that is still a significant number, despite the eBay announcement making it seem insignificant.
Total number of US zip codes: 41,683 (Source: www.geographyrealm.com )
Number of US Zip codes affected: 17,810 (Source: Excel sheet provided by eBay through rate change announcement)
