I was looking at Car-part.com for an airbag because I was thinking about how some people said a replacement airbag costs $800 but when I started looking around, I saw that they've got a LOT of listing for airbags and the cheapest I've seen is $45 for the module which I think is the most expensive part, right? Can somebody explain to me the huge price discrepancy!?

 

Brand new ones are expensive, used ones aren't, I got my steering wheel w/ airbag for $20
