Dont always sell stacks of everything, it's annoying, sometimes we only need 2-3 items and we don't like being forced to buy 99.

They'll sell, I guarantee! Could even price it much higher than usual price.

I'd rather buy 5 iron sand at 100 each than 99 at 20.

Obviously that doesn't apply to everything, shards and stuff are best bought in bulk, as are most items that need to be transformed to be usable (flax, ore, etc). Just do some research on what mats are used in which recipes, and I can guarantee you'll make crafters happy, and your wallet as well!

Thank you.
