Check, Check and check. To each his own, but most replies exemplies all of us.
I, personally don't offer trades, but sure as hell get plenty. One of my 2020 resolutions was to handle trades a bit differently. 1. I check this site daily, which includes trade offers, and I always look at them. 2. I might respond at once, if it's an easy one, all from 1 box etc. Multi-card trades of @100 I need time to think. 3. what annoys me is a massive trade, that I barely look at and then it's withdrawn. ehhh 4. keeping @5 offers live, while working to pull, pack and ship @3. 5. and somebody said it, good COMMUNICATION is so important.
So far in 2020, my different approach is working. Trades are viewed, communicated, accepted, pulled and sent in adequate time, especially for a notoriuosly slooooowwwww trader.
Also, because of the glut of cards I can trade, I may often draw attention to them in a forum post and request a PM for more info. That gets many bulk traders rolling. And there is the Up for Grabs offer that moves the inventory I just need to move.
There is so much help we can offer other traders, if we can remain civil and patient. But COMMUNICATE often.
