Do you have pins on your Wants list that....
I don't see what they're beating me to. He asked me to trade. So I feel that why would they ask me to trade when they can't do the trade. That's why bulk requesting is frustrating
The theory (and it's a very likely one) is that the trader offered that pin to ten, twenty, fifty different people (of which you were one), and someone got back to the trader to finalize a trade for that pin before you did.
