The ideal concept for this one would be to check a box or something that we are not buying goods (crops/tree products/flowers/fish, etc.) at the trade market. I CONSTANTLY get people trying to sell me directly (and many at market price where it wouldn't even give them a FP quest). Even if I change my avatar to "Not Buying" it rarely helps.
Alternative if there can't be a check box to block it, adding a color dot (just like the greens are) that's a very obvious color (such as pink/red/bright yellow or something) that indicates we do not want to buy products directly from other farmers.
It drives me crazy I constantly have to say/click No because people try to randomly sell me stuff. I want the ability to indicate I am willing or not willing to buy.
I have accidentally clicked yes on it a few times and maxed myself out unintentionally with acorn squash
ugh! My fault for clicking the wrong button - but it would REALLY help if we could block people from selling it to us in the first place.
