WalMart has Linksys' top tri-band router on sale for under $200, while the Linksys website has the same item for ~$250. I believe the "RM" designation means it is certified refurbished so it comes with a 90 day manufacturer warranty.
Benefits of this router: 8 gigabit ports (versus 4 on most routers), MU-MIMO to maximize bandwidth over WiFi, tri-band wireless, and a 1.4GHz dual-core processor. Typically $350-400 brand new.
Free shipping, and doesn't appear to allow for in-store pickup, at least not in my area (61801)
