Seller Silence

The seller could have multiple offers to buy and is working with the most likely to purchase. See if the item is taken off the market or marked as sold within a week or so.

Out of courtesy they should at least respond.

Funny you should mention that.  I was communicating with a seller and when I asked about if there was a warranty, they flipped out and said stop wasting my time.  A simple no would have sufficed.  I ended up buying from someone else.  I don’t understand sellers that ghost.  Are you trying to sell it or not?  I’ve had plenty of questions as a seller that could be upsetting but I let it go because I’m trying to sell the equipment.  Let it go and move on.  There’s always another seller.  

Count to 5. That is how long it would take for a seller to respond, even if the response is no. It may just be an indication of rudeness but it also may be a warning sign that dealing with this seller if something goes wrong would be very frustrating. That is why I think there should be a way to allow pre-sale comments.

You want to be able to leave poor feedback for someone you didn't transact with because they didn't answer your question? This isn't facebook where you engage furiously with people at will. P.S. You don't know that used gear is no longer covered by the OEM warranty and that the warranty only applied to the original owner and only if purchased via an authorized dealer?

I think there should be a way to allow pre-sale comments.

That would also work in reverse then, right, where the potential seller could leave feedback on you? Such as:

"Avoid this tire-kicking seller like the plague. I don't know who this guy is but he popped up out of nowhere and his first question was if there was a guarantee on used merchandise. What a laugh! Don't let him waste your time."

To be clear, as a buyer, I understand your disappointment. It's happened to me here. But I prefer to see a seller's non-response as just a good reason to avoid that seller. So I move on.
