Lifeline Olympic Bar and Bumper Plates

If the bar is purchased, how many plates come with it and which ones?

No plates come with the bar. You buy the bar and then the plates you want to go with it.

Is it 1 set of plates? If I buy 15 lbs, is that 2x15lb plates, one for each side of the bar?

Each plate is sold individually.

ehh, I might consider buying the plates. But that bar, ya I would not trust it at all.

12/11/2016, Sears has the Weider 300 lb Olympic set for $179.99 w/free in store pick-up. Not sure how long this deal will last.
Not quite as fancy as these plates, but it’s a significant savings.
