So, about 4 days ago, I bought a crazy-expensive item on accident. I was trying to bid on an item, but I accidentally hit the buy now button (Hey, I was tired). So, I ended up buying a piece of Emberbreak armor with a less-than-stellar UV for 20,000 CR, which was all of my money at the time. Ouch!
The bid price was rather low, and I like to place a bid or two on something that looks like it has a decent value.
So, In my disappointment, I relisted it starting the bids at 1 CR (anything I sell, I list as bid starting at 1 CR, generally). Sold the next day for about 550 CR.
That day, I decide to sell some materials to try to make some more money (along with running through levels, of course). I went to class, and when I got back home, I collected my money from the items I had sold. This happened.
If you can't see the image, I sold a green shard through bids, for 5029 CR. That pretty much made my week, even more-so that I had that huge loss just the day before that.
So, thank you very much, anonymous market user who bought my item for a ludicrous price, you really helped me out.
