While buyer may be new to the trader, this is not marketplace! If you have questions, want additional pics or negotiate price... be sure to do that before committing to "I'll take it!"
If not wanting to commit until visually inspecting item, then be sure to make that clear in conversation.
I almost backed out of deal and almost left Neutral/Negative feedback.
Mr. Haarwood
He was selling an item for $100. After we arranged meeting place and time, I asked “Btw would you take $80 for it?”, knowing full well that if he declined I would still pay $100 for it. After he declined, I said “no problem $100 it is, just shooting my shot” since I forgot to ask earlier. I get that I should have asked earlier, but no need to make such a big deal about it adding it to my review.
