Sell in stacks of 5 or 10. This allows you to charge alittle extra per bar, as people buying bars to craft might not want all 20, maybe just a few.
For example, say copper is 50s for 20 bars. That'd be 2.5s per bar. Sell 4 stacks of 5 for 15s ea, 3s per bar. You get more money, they sell faster, and the buyer doesn't 'waste' money on bars he doesn't need. Everyone wins.
The exceptions are Silver, Gold, Truesilver, and Arcanite. Sell these as SINGLE bars. Stacks of these never sell well. Most recipes only call for only a few (if not one) of these bars, so not many people are interested in stacks of them. Truesilver for the smithing quests is in some demand for stacks, but you'll cut your market in half selling in batches.
Gems:
Keep track of what gems sell and what ones don't... and how well they sell. Each server is different.
I know I can charge triple the starting bid on Malachite, Tiger's Eye and Jade. But Shadow Gems are less than double the starting bid, with Aquamarines in no demand whatsoever. Therefore they are vendor trash.
The holy grail is the Arcane Crystal, used to make arcanite. Charge major molla for this. Then again, they are extremely rare mine from Rich Thorium veins.
Stones:
Same as bars, stacks of 5 or 10 sell faster. Still, full stacks sell pretty well, as they are used in consumables as opposed to permanent items. Therefore anything they don't use now they can store in their bank and use later, as opposed to having to resell a partial stack or bars back.
Do NOT just vendor them, they will sell. However, they will not sell at nearly the markup bars do. There's a demand, but the items they make are by no means a necessity. Still, easy money.
Seems Solid Stones are in HUGE demand right now. (Mithril / Truesilver stones), so you can mark those up abit more than the others (about double default bid is a good starting point).
NINJA EDIT*********** Pricing buyouts
Oh, ALWAYS put a buyout. People want their stuff NOW, not tomorrow.
And put the starting bid at half the buyout. Seeing a 15s starting bid (default for 5 bars of mith) for a buyout of 1g makes people leery... thinking they are getting ripped off, maybe just put up a 35s bid and let it ride.
A 50s starting bid and 1g buyout makes people more comfortable with the buyout.
Perhaps even put the starting bid at 80s (80% of buyout), but then you increase your risk of people looking over your stuff for something cheaper. Only put the starting bid close or equal to the buyout on stuff you KNOW will sell (like Iron and Mithril)
