I think
ebay believe their intentions are good, and that when Best Offer is on an auction item, it is looking for a genuine reasonable value. We aren't buying a bunch on
ebay at the moment, but I know there were times in the past where I would think "I wish I could offer some amount, and just be done with it, rather than getting snipped out by 5 cents at the last second. (I wish
ebay would do away with "cent" increments on items that have start values at least over $10 anyway... but they don't). The problem is
ebay buyers are already conditioned that "best offer" means "lower than what the current price is". I put up an item with a start value of $50, knowing that it would go for a lot more, and I got 3 offers in about 30 minutes that were less than $45. I replied to all of them saying essentially that I'm not an idiot, and that this feature in auction is intended for reasonable price offers, not "low ball offers" just to sell something, which they actually understood (I phrased it more eloquently in my responses to them). So I think mostly this is an "education". It will take time for it to correct, and the buying community to get used to this feature. In the mean time I've just taken advantage of the feature that cfrphoto points out, in that I automatically reject offers below a reasonable amount I would take for the item, and then I don't need to respond to such trivialities.
I think the major disconnect I'm seeing though, is in those using a 3rd party tool to manage listings, rather than using the
ebay on-line tools. Here I think is where
ebay expects they don't need to "educate" sellers because the forms are reasonably clear, and a new feature is identifiable. In the 3rd party tools though, they are not, and defaults in the updates that
ebay make are not reflected in 3rd party systems until they are updated.
I completely get why people use 3rd party systems. But, I can see there is also a point to be made for using their online tools, because updates are more easily recognized.
