Also, if you are penny pinching for parts then, you have no business doing a restoration. Nothing is really cheap here.
We all use the term penny pinching pretty loosely somtimes I think. But I don't call it penny pinching when one place has a metal bracket for $20 that I can get at another place for $10.50
Yes its good to be able to get all your stuff at one time if you can and from the same vendor. Making a lot of orders from different places no on wins but the post office or other carrier.
Bottom line is what someone said earlier. Do you homework and check the bottom line.
