This is one of those sites you need to pay attention to every little detail. This is a good site if you know what you are looking for and looking at its not as user friendly. There are things some people don't realize they need to look at for various parts.
-Brand- There are various brands and good amount of known ones to be reliable. If you don't know what is do research or ask someone who is a car mechanic. To many people go cheap cheap then they get what they pay for...
-Part # and details- Some parts are set-up differently and are made for different locations I.E. Left/Right, Front/Rear, Upper/Lower. Spark plugs will either be in the right depth or not you need to check. Just be careful of alternate parts sometimes they work sometimes they don't but if you are not sure stick to th OEM based models.
-Cross reference sites- Check with like auto zone of similar parts based on the part # and look at prices sometimes you can find better deals on part on amazon.

The thing about this site also it has pretty much every part for majority of vehicles so not every site is like that. I have years of experience when it comes to ordering parts and if you know the systems for doing so its not hard to do but if you are just fixing your own or a buddies vehicle and are not familar in ordering parts and use to going to the store yea you might mess up and not get what you wanted/needed.

The delivery with rockauto is not the greatest using Fedex and USPS which have a bad rep and it's mainly their fault for stuff being broken on delivery so would have to place most the blame on them.

The site works and is great value if you know what you are doing and looking for if not you are going get annoyed. I've gotten numerous parts from Rockauto over the years and they have worked as intended and still no problems so far. So some quick advice

-Don't go economic for most things because they won't last long stick with daily driver.
-Make sure the part you are getting matches the specs you need if not sure to look at ask someone who knows. Some people also don't know the full model of vehicles need to make sure of that because some differ in major ways
-Stick to the return deadline 30 days this is one of the companies that you have to also pay for the shipping of return. This is not amazon they don't make that kind of profit like them since they pretty much sell everything at factory price and that's hard to come by in online retail.

If you pay attention and do your due diligence on most of this you will get your bang for your buck if not it will be a headache for sure.
