Counter Offer/Haggling

It might be nice if the trading post had a means of responding in the trading center itself to an offer you are interested in, but feels like too low a ball? I get that you could message the person directly, but it may be nice to be able to more quickly and directly negotiate prices with people and encourage people to offer, rather than just autobuy. Eg I have trade X that I want Y herb, someone offers me Z herb, which I may be interested in, so I offer R herb instead in case they are interested in that. Or, for example, more simply speaking, I ask 300 for a puppy, they offer 150, I counteroffer 200, etc etc

At minimum i support the idea of being able to post a response! Maybe not a full on bargaining system , but I think it would be pretty useful to at least have a way to be like "hey, i saw your offer for 150SC, how does 200 sound?" to let people know that their offer is quiet good enough to pick up right away but maybe not bad enough to get rid of

that way people can know "hm, this offer isnt quiet good enough but not being rejected- maybe I should try something else before its bought out" 

You can already enter a message why you declined an offer. Say you get a 150sc offer; write in "I want 200" and the other player can then decide if they want to offer again.

And if its more complicated you can move the conversation to PMs to haggle before they sent a last offer.
