I bought some body-panel clips for a '97 Camry on ebay. They were the push-in type clips/rivets for the bumper cover. Got 30 of them for $5 from a seller in Hong Kong. Took a week or two to get them, but not problem with the transaction. Looked and functioned just like the OEM kind. I actually used two of them recently on my Ridgeline when I noticed the air-intake was loose. One of the clips was missing and another was a little loose, so I used two of the Camry clips to tighten things up.
On the other hand, my wife ordered some bracelet from a seller in China for $4.25 and still hasn't gotten it. According to the tracking information provided, it apparently made it to the local USPS sort facility back on October 20th, but it still hasn't been delivered.
So one went well. The other didn't, but could possibly be resolved.
