That's one thing you don't do, is get a few deals at a certain place, and then get complacent and don't research anymore and just buy everything there. Walmart is bad about that. You get some good deals on food there, so you just start buying all your food there. Don't do it. You can sometimes get a better deal when another grocery store has certain things on sale. My wife goes to several grocery stores sometimes.
Same here with Rock Auto. Always check around at other places. Amazon will get them sometimes. The best thing to do is start at Rock Auto, and they will give you all the part numbers. Then start plugging these part numbers in a general google search. Just the part number, maybe the brand name if nothing comes up. If you do a search for "2003 Super duty axles", that will bring up the higher priced payed for hits on google. But if you have the actual part number from a vendor and plug it in, different sometimes cheaper hits come up.
