The "effective June" announcement does not cover promotional efforts.
Currently, PowerSellers get "free" sub-titles and double FVF rebate when offering "free shipping". The original promotion ran to December 31, 2008, extended twice to June 30th.
Will eBay extend it again? Too early to tell.
The extension from March 31 to June 30th was announced on March 4th. Check the http://www2.ebay.com/aw/core/200903041438042.html
The earlier extension from December 31st 2008 to March 31st 2009 was announced on December 18th. Check the http://www2.ebay.com/aw/core/200812181208312.html
I wish eBay would give sellers a bit more time to plan our marketing efforts. However, this is eBay and seller support is not something they are very good at - as we all know.
