In an interesting twist of events, eBay announced last week that third-party checkout solutions will no longer be supported on eBay after June 30, 2011. eBay says that other checkout solutions (besides PayPal) are only used less than 10 percent of the time on eBay.com. UPDATE: It’s come to out notice that eBay never offered Google Checkout as a payments service on its platform. The post has been amended to reflect this news.

As a peace offering to those who do use other checkout systems, eBay checkout is being upgraded with a number of features including advanced tax reporting, more credit card integration, and advanced shipping solutions.

Clearly eBay is looking to only expand the use of PayPal, which is currently one of the most popular payments platform across the web.
