Steam offers downloads of Portal 2 for Windows Mac for $4.99. (Steam also offers downloads of a Portal 2 2-Pack for Windows and Mac for $8.74.) That's tied with our January mention as the lowest total price we could find by $15. Deal ends April 22.

Haven't played either Portal game? Steam also offers downloads of Portal 1 and 2 for Windows and Mac for $6.24. That's $2 under our mention from last spring and the lowest price we've seen. (It's also $24 under the best price we could find for downloads of these two games purchased separately elsewhere.)
