Not too much of a complaint but here was my recent story.
I needed some expansion/freeze plugs for the heads I'm working on. Just stock 3800 Series II heads. I found the part number, went online and O'reillys were the only ones that could get them. I called them up Monday night and spoke with a guy. Gave him the part number and said he doesn't have them and could get them by tomorrow. Not a big deal. I gave him my number and he has my name and I said thanks and I'll be over tomorrow night.
Last night I run down to the store after work (Westerville Rd). Some lady is working there. I told her that I had something ordered and it should have been there (somewhere). Gave her my name/number. She looked it up in the computer. Nothing. She goes and checks in the back. Comes back. Couldn't find them. Then asks me what car it's for. I said don't worry about it, you won't find it. I had the part number memorized. Gave her the number. Still couldn't find it. Apparently what I found online in 2 seconds she couldn't find on their computer.
Then she goes back again and comes back with the bag. She said the other guy was hiding them from her (sigh).
So that process took 15 minutes (13 minutes longer than it should have). Not that it matters much but when I give direct part numbers for things that I found on your site, you should be able to look it up on your store computer and not have to look up what year/make/model what it's for.
