Amazing Deals Online via Amazon offers the refurbished Linksys Smart Dual Band 802.11n Wireless Gigabit Ethernet Router, model no. EA3500, for $29.85. Coupon code "EA3500RB" cuts that to $20. Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $11.53.) That's $19 under our mention of a new one from last July and $49 less than the lowest total price we could find for a new one now.
