Just picked up a 2oz bottle of r-0871 fas-dpd re-agent and a 10 gram bottle of dpd powder r-0870. Both sold by a third party seller but stocked/shipped by amazon. Only problem is, they both have a 6/24 expiration date, which is only 8 months away and not the 12 months Taylor advertises. Did I get ripped off or are these typical expiration dates for Taylor supplies?
