Uhm. I'm not sure wat happened there, but I just sold 25 Shamrocks, and I'm fairly certain that I had put them in at 62.500 gold? Maybe it was my mistake, but they just sold and I got 625.000 gold... there are some for sale for as much, but then there's also a lot at the price I thought I had put in, so I can't imagine anyone would have paid that much for mine at this moment? I don't know, it does seem strange, so I thought I should probably report it in case it was a bug and not a lucky typo on my part... and I certainly didn't plan to rip anyone off :/

There isn't anything that would change the price once submitting and it takes it directly from what you input into the box. According to the database, I see that you sold 25 Shamrocks listed at 25,000 gold each - which totals 625,000 gold.

Since the price is very visible when a player buys a listing, the buyer knew full well how much they were paying and must have been okay with that amount.

Hm, OK... guess I got some money then...
