Did not know you had '96 cool more info?
Autozone if it's name brand, for instance Bosch, can be ok, or for tool if it's not critical thing you use all the time if it is get the waranteed one, if at all. Harbor Freight also about the tools/accessories.
Rock Auto good, but they don't have some things (usually they do). True, shipping can be a big hit if you get 3 things and they all come from different places which I don't think you can know beforehand. I've had good luck emailing Customer Service there. Amazon -can- be ok but make sure it's exactly the thing you are trying to get. Ebay good, really haven't had any significant problems there. Summit is fine, tends to be high end from what I see but sometimes you have to go there.
NAPA fine as always but a lot of stuff they don't have and will be in some cases basically 2x what you can get the same thing elsewhere (I mean exact same thing). But if they have it in stock and you need it right away, they're a possible. O'Reilly can have some stuff.
Ebay/Amazon make sure it says returns ok.
There are junkyards, again just depends what it is, but I got a real nice replacement seat belt for the Mazda and cleaned it up and it's like new.
Lots of times people here will know where you can get something if you can't find it.
And lastly if you really can't find it, which can happen, post here in Parts Wanted. However watch out because I *think* there are scams where people look in forums and reply to posts looking for parts, usually in DM and say "My friend
xxx@xx.com has this part" so you write them and they're like yes I have it then you send money, probably more than it should cost but you're desperate so you do it, then they say the shipping was way more than they thought, send more (I didn't) then they never send the part. Ask me how I know this. And whatever you do unless you know who you are dealing with don't Paypal "friends and family" because
you can't get it back. I didn't send it that way because I didn't know wtf they were talking about.
On the other hand if the seller is somebody actually on here and especially if they are frequent poster and are well known, you're probably ok.
F/F is something I just learned about. Luckily Paypal refunded my money in 2 seconds when I told them I never got the part. And I did get it finally from a guy on here and had
zero issues so I guess the lesson is deal with people you know and/or don't send F/F until you establish a relationship. Something like that.
If you know the seller then F/F is better for them because they net more of it so just because somebody says can you send F/F it doesn't mean it's a scam. But if you are trying to deal with somebody "off the books" (not a forum member and all you have is an unknown email) - be careful.
I guess even though I never had to do anything really major, I've dealt with a lot of places. A lot of times people on here know where you can get something that you can't find and can point you to the correct part and supplier and that's really valuable info, so when in doubt, ask here.
