With activation of a new 2-year contract, Best Buy takes up to $100 off select smartphones, with deals starting from $0. (Prices are as marked.) Plus, most items qualify for free shipping. (Some require in-store pickup.) That's the best dollar-off discount on smartphones we've seen from Best Buy this year, yielding several price lows. A $35 activation fee applies. Deal ends October 26. A couple of best bets:

• Samsung Galaxy S III 4G 16GB Smartphone for Verizon in Pebble Blue for free
• Apple iPhone 5S 16GB Smartphone for AT&T in Silver (pictured) for $99.99
