I know that feel. Collecting by ourselves in game is to be honest the best if we want to savor everything! xD Oh and I'm mostly the...kind of expert of regional exclusive thingy. I'm like, say, a pipe. Korean friends/European friends keeps throwing their holiday items away in my town regardless what I say. So I provide these items to my other friends. Then they give me their items, and I give those items to others, and on and on. Now my town is almost flooded with those stuff. Its already helpful if you could take some off my hands. What item are you after?
