HOW DOES THE BUYING AND SELLING WORK IS IT LIKE EBAY OR AMAZON IM SO CONFUSED I WOULD LIKE TO BUY AND SELL BUT HOW AND WHAT IS IT DO YOU PUT IN A CODE AND IT COMES UP IN YOUR GAME OR WHAT?
SOMEONE PLEASE EXPLAIN!!
People will trade their goods for other goods or bells (money).
If they get an offer they like, they will accept it.
After that, both parties add each-others friend codes.
They then visit each-other in a town and do the trade (by dropping and picking up goods).
There can be scamming (stealing) done by this method but this is really the only way. If someone scams then they will get a bad reputation on here and most people wont want to do a trade with them.
You could also run an auction thread if you wanted.
