This is a rapidly changing retail environment. And not for the better in many cases.

We have been in business for nearly 40 years and find that we must frequently adjust our attitude on many things. Not happy about that. But that doesn't mean that anything goes, either. It's just that how much money are we willing to risk and how much more complicated are we willing to make our buying? We have had issues with most of our largest suppliers at one time or another and not all were resolved to our satisfaction. But we have to weigh the big picture. Some suppliers like RockAuto, 440 Source, Ebay, etc are not replaceable in our business and personal endeavors. Sometimes we just have to hold our nose and push ahead. We are particularly hesitant to use Ebay. They just suck. But to totally eliminate them would not be wise. We just shop hard to limit how much business we do with them and if it is a close call, they don't get the sale.

Maybe these decisions can be different in a hobby situation than a business situation. Maybe if you don't need a steady stream of parts, you can occasionally eliminate a major supplier. Maybe.
