Chromecast – Walmart (instore) or BB after price match (YMMV) $9

This is a big YMMV. I was able to replicate it twice.
Walmart in Linden, NJ has the Chromecast for $9 in-store only. I live chatted Best Buy asking to price match. Best Buy price matched it twice with no problems.
Model: NC2-6A5
You need to copy and paste to see the $9 price. walmart.com/ip/Google-Chromecast/46708712?wmlspartner=wlpa&selectedSellerId=0&wl13=3469&adid=22222222227034410877&wl0=&wl1=g&wl2=c&wl3=74766690152&wl4=pla-144746898032&wl5=9060351&wl6=&wl7=&wl8=&wl9=pla&wl10=8175035&wl11=local&wl12=46708712&wl13=3469&veh=sem&gclid=CjwKCAiA9efgBRAYEiwAUT-jtJRTh9ttm4hBumBnObIwL5SsDEbQoPviJBmweFHPRLJLruObZs-8aBoCwT8QAvD_BwE
