I know this has been a topic in the past but I thought I'd share my recent experience.
I bought 4caps from AliExpress for $8.24 delivered. It took 9 days to get to me.
I know they're not OEM and since my car is far from a show piece, that's fine by me.
They fit VERY tightly so I'm not sure if they'll survive removal should I need to, but I also don't think they'll fly off while driving.
