Ebay sellers - "Package Included"
When browsing ebay listings, too often I see them writing "Package Included" as the heading when listing the items included in the auction/sale.Why do none of them realise it should be "Package Includes"? Otherwise it seems like they are saying the packaging is included, which is a given anyway.
This wording is predominantly used by sellers in non-english speaking countries (such as China). Why is it so widespread? Do they simply copy each other''s mistakes?
