or in store. Additional $20 off if you bundle with CPU (depending on availability).
Not an amazing discount by any means (this is the MSRP I thought) but if you are like me trying to build a Ryzen ITX system you know the mb has been on back order everywhere recently. Now that B450 boards will support Ryzen 4000 as long as you don't need PCIE Gen 4 this is a pretty good deal IMHO. The only B550 ITX MSRP I heard about are MSI ($199) and ASUS ($219) - release date June 16th. I choose B450 for my needs.
Before someone in the comments start talk about the rumored XT series of 3000 CPU's and argue that you should wait a month or so - I would argue that it might not be worth it for all considering the current discount you get on 3600/3700x etc. Unless XT gives you 20%+ performance bump. Nobody knows at this point so use your own judgement.
