seller etiquette

@viridian that’s not how my brain and moral compass works but thank you for the explanation. I think it is fair to assume that when a local pickup is arranged, the point is to bring cash, look at the goods  and then go on our merry ways. I could be mean to a lot of people without any consequence, I can put dog poop bags in my neighbors’ mail box but I will not do that because I am a decent human being. I would rather bake a cake and put that in their mailbox.

Telling the user what guarantees a sale (e.g. I might change my mind at any minute, if you don’t pay now is a swell approach)

Lastly I still don't know what the feedback has to do with it.

No honor in capitalism. Seller's goal is to get rid of it immediately. The market will bring you something.

That sums it up. We are monsters, not humans.

@parkergetdean 

since you were not going to even test the unit at the sellers locale, why not just pay in advance?

  We once saw a piece of furniture we wanted.  My wife likes to ponder, so she told the store owner that we would be back in a few days to buy that floor sample.  We returned to find that was sold the previous day.  Neither of us blamed the store.  A bird in hand, etc.  I don’t see any difference here and at least you were notified before making the drive 

My wife sells things occasionally on fb marketplace.  Pricing is agreed to upfront.  Probably 65% of the time people try to renegotiate when they pick it up.

Unfortunately, you are in the minority (as am I) that your word is your word.

I can't fault the seller.
