Opinions wanted in regard to unsolicited offers on cards
I thought it would be cool to have an open discussion on what is, or is not the appropriate way to make an unsolicited offer for a card that was posted by a collector to show off on this site, sketch collectors, etc (ie not a card posted to a sales thread)
Which of the following are most appropriate:
A) is that card for sale?
B) How much for that card?
C) I will offer you ($ specific amount) for that card shipped to (specific country)
D) nice card, let me know if you ever want to sell
E) it is never appropriate to make an unsolicited offer for a card not posted for sale.
I have my own opinion, but I thought it would be cool to hear others opinions before weighing in.
