Amazon offers Prime members the ExOfficio Men's Give-N-Go Boxers in several colors (Charcoal pictured), with prices starting from $10.99 with free shipping. That's $4 under our mention from last October and the best price we've seen for a single pair. (It's also the best deal we could find now by up to $7. For further comparison, we saw two for $21 shipped last December.) They're available in select sizes from S to XXL.
