Yep - Ever since trying ebay postage policies recently, we keep finding they are getting removed by ebay somehow and being bot replaced with some ridiculously high charge, making listings have no appeal to buyers. We then have to manually go through every single listing and eyeball whether it has the postage policy still applied or the ebay random bot price increase. It's really, really tedious and annoying. 

It may even be fraudulent on ebays behalf? Randomly jacking the postage price up for no logical reason, on the sellers behalf?

I hope they fix this.
