Li Yong-Rui systems give 15% discount on all ships and components, vs the 10% off at Jameson.
I bought mine at LHS 20/Ohm City a year ago. However, I'm not sure if they are still sold there or not. Things change over time. If it isn't there, you could try elsewhere. It was sold at Diaguandri/Ray Gateway for a bit (I was surprised to see it there), but eddb.io isn't listing it there any more. EDDB is indicating that they are sold at LHS 20/Ohm city as of 20 minutes ago.
An extra 5% might not seem like much, but the savings add up and it also lowers the rebuy.
Hope you enjoy it. I don't use mine as much after converting my trade Anaconda (which had collected dust once I got my Cutter, right around the same time I got my Corvette) to a full combat/multimission role. I prefer the load out on my Anaconda and the increased jump range. Occasionally go back to the Corvette for the different look/load out.
One last tip, if you use
Coriolis to spec out your ship ahead of time you can click on the $ button in the top right corner and find stations that sell your build and then sort by Power Play Power (listed as Power) to look for LYR discounts.
