Based on covid pricing, the plates at $1.13/lb is a steal. That's what they are generally worth before covid. I wouldn't worry about the weights. Rogue quotes 2% on their steel plates which is 0.9 lbs. I would get their even if they are 2 lbs off, unless you have better deal elsewhere. If it's your home gym, just mark them with a sharpie and use steel washers to offset any real bad difference. A 2 1/8" washer is about half a pound.
