I hear you on this.
I often make multiple shopping lists from various vendors, and each part number I read off to the order taker I ask if it's in stock. If not, I say strike that part from my order. I then shop that part from other vendors.

It is a huge pet peeve of mine, that a seller would send you a catalog of parts but do not keep them in stock. Even worse, if you order it then wait and receive the part only to find out that they ordered it from another vendor and sold it to me with their mark up.
