Walmart offers the D-Link AC750 802.11ac Wireless Dual Band Router in Black, model no. DIR-813, for $24.95. (Amazon has it for the same price with free shipping for Prime members; Newegg charges a few cents more via coupon code "EMCEJEK36".) Opt for in-store pickup to avoid the $4.97 shipping charge. That's the lowest price we could find by $5, although we saw it for $5 less in March. This router features both 2.4GHz and 5GHz bands, up to 750Mbps data transfer rate, and four Ethernet ports.
