Yeah I agree, and they should also guarantee us that 27.75% of our goods will sell each week.  And that all buyers will pay us within 10 minutes of purchase.  And that no buyer will give us negative feedback.  They are all issues that sellers complain about.

Ebay are a business, they suit the free listing to periods that suit them,  that could be periods of low listing, or a multitude of other reasons.  But it is done to suit them, as you do things to suit your business.

And just thinking about it I think they should make that 36.25%  rather that 27.75%, that would be even better.
