The following was just posted over on the eBay AdCommerce blog:

In order to focus on the best selling and shopping experience, the specific AdCommerce program that allowed eBay sellers to purchase pay-per-click advertisements on search result pages linking to their eBay stores and listings will be retired for eBay.com and eBay.ca as of August 4, 2010. The service will continue for eBay sellers using AdCommerce in Europe and Australia.

According to the blog post, those that have recently purchased AdCommerce ads for their store or listings don’t need to do anything at this time because the placements they’ve already purchased to appear on these sites will automatically expire on August 4 with final billing to be sent out in early September.

The AdCommerce team is in the process of proactively contacting sellers involved in the program via email and phone call.
