"PSPRSINGTIME" will get you 15% off anything on ebay right now (just once). But it has a max value of $50 off, which means the best bang for your buck comes on items priced less than $333. Conveniently, that's about the going rate for a YH or Tuxing single piston - so you could get approximately an additional $45-50 off the thing. That's a good deal.
I know the max discount kicks in bc I was trying to apply it to a Condor SS. Oh well.
