I have a gold account, I've been paying 1000 SC for these, September 2012. So apparently SoE decided they were undercharging, or it was an "introductory price"?
I bought one also for 500 sc and found out after the fact that this will only hold tradeskill items. :( Still a nice bag for those pesky TS drops that clutter up your inventory.
Admins: Please make the comment about the Tradeskill-only a bit bigger of move it so it stands out. I couldn't see it so it came as a shock to me when I learned about the TS only use.
I know that now. I've been in retirement for the past half a year. Some of these new things that have been showing up have enticed me to peek in and have a look around since EQ is now free to play on a limited basis. A lot of things have uses but mostly it's just fluff. This item deffinitely has some uses.
