What's the rule/etiquette on trade offers? Context: I have a couple of sale pieces that I'm also interested in trading. Getting lots of PMs with trade offers. Is it like sale offers where the seller should deal with each in order, or is there a different but fair way of handling trade offers? I mean, I'm in discussions with a couple of members, but then a better trade offer comes in! And what if a sale offer suddenly comes in. Just abandon all trade discussions? Don't want to cause any offense so advice from experienced traders appreciated.
