If you can get 10 for 14.99 that's not a bad deal, you just have to buy in bulk. You could then turn around and try selling 5 of them on ebay for $6 or something.
Searching around at places that sell bearings in bulk, the general price seems to be about $20 for a lot of 10 in that size, so if you found them for $15 I'd say that's a good deal.
I also agree with you, searching through any of the car related threads is pointless as the search function does not take you to the specific post, or even the page, it's kind of mind numbing the way they have a entire thread per subject/car rather than an actual forum category for it.
It would make way more sense, and be more organized if they had it setup so each huge thread had it's own sub forum rather than just a thread. You can't search, and most of the posts seem to be chatter back and forth between guys who know one another, or it's totally off subject. Now that's clutter.
