I know the owner of this online store, personally, and he does not stock everything he has online. He is a marketplace where other merchants post their products. Most of his stuff he has in stock, but other parts such as gears, sprockets and chain are ordered from other distributer, then sent out to you. The robotmarketplace is a great place to buy robot parts. Just keep in mind that you should buy most of your mechanical parts from mcmaster or other distributors
