Buy.com has a coupon for $20 off $100 worth of D-Link products. D-Link mainly makes wireless routers, bluetooth adapters and networking gear, among other things. Since many D-Link products have large rebates, the coupon can be put to several good uses, including this blindingly fast D-Link 108Mbps Wireless Router with USB adapter, normally $108 but now just $48 after the coupon and a $40 rebate. Shipping is free on most items and there is no sales tax (except to CA, MA, MD, TN).
