I'm looking for a guide rod spring for my Witness, a Pearce base plate for my G29, a grip extension for my M&P, and an extra magazine for the Witness. Looks like I have to pay shipping from two different spots.

I've looked at Brownells, Midway, and Cheaper than dirt.

Yeah, it sucks, but it's just how it goes sometimes. 

Have you tried Numrich, i.e. Gun Parts Corp ?

Well I put in more specific search words on the Midway site and found everything I was looking for. Since I'm cheap I'll wait a week before I place my order so I can get my birthday savings.

Well there you go !

I hear you about frustration of shopping so many different sources.  You should see my reference sheets for AR builds.  Nine different sites and counting.  And I bet it will grow some since I am not buying it all now.

Try buying powder and primers. Occasionally you can find 1 kind but not the 2-3 other brands you want at the same online store. For these items not only do you get to pay shipping but a special Hazmat fee as well.
