To me, if you place an ad it is common courtesy for the seller to quickly respond to questions. No or a very delayed response is a “Red Flag” warning ⚠️ . Do you really want to trust this seller to complete the sale without delay or issues. When I experience poor seller communication I just move on to the next listing…
Seller Silence
On two occasions during the past month I have posted a question to a seller about whether the item still has a manufacturers warranty. One selling an Aurender N20 and the other a JVC NZ700 projector. Neither has responded even though it has been a few weeks.
There should be a way to leave seller feedback before a sale to inform potential buyers of this issue.
