eBay , if you use the search function to find help topics it returns an error page.
To be honest although they’re working to fix the problem it’s no great loss. ebay’s help search is, to be frank, not that good. If you’re trying to find a help page it’s much easier to search on Google. Simply type the search into Google, instead of the eBay search page, and append the word “eBay” to your search string. Nine times out of ten you’ll get more relevant eBay help pages than by using eBay’s own search engine.
Don’t tell eBay I said so though, asking them to implement a Google custom search engine on the eBay site might not go down too well 😉
