I just started a new commodity vendor. Nathaniel occupies stall I-3, which is right off the northern bridge from the bank. He's both buying and selling various resources. Currently he's got hides and some imbue stuff. I will be adding ingots. I plan to be adding more things to him as I go along. Sorting things in my house etc. I am doing Vendor Searches to ensure that my prices are the cheapest on the shard for selling. I am also buying at the best prices for most things.
