its annoying to have to go to the shop every time to sell ur stuff, i know it would take a while to set it up, but i think it would be worth it
It's a nice suggestion but personally I feel like it would be a lot of work to make this. It'd also have to be updated every time a price is changed. And we'd be hearing 24/7 "why isn't _____ working with /sell" and we'd always need to respond "Because you can't sell it in the shop". Also if players never really visit the shop then plots kinda become useless too.
Well the purpose of our economy and the reason it was set up as it is was to try to make it harder to make these huge bulk farms. We want players to actually have to work for their money, not have it handed to them on a silver platter.
Not having bulk sell signs doesn't stop anyone from making huge farms and selling the items they get from those, I mean have a look at islands of the people on /baltop. I'm pretty sure most of them have massive farms on their islands or an alt's island (not counting six and dum as theirs were removed) and yes, I'm including myself in this.
