Amazon is running a promo that gets you The MAW, Drip Drip, and Ticket to Ride for free when you buy any one of 422 (not a typo) indie games starting at just $1.99. My pick would be either Ticket to Ride USA 1910 DLC because it pairs so well with TtR, but Scribblenauts Unlimited for just $5 would also be another of many great choices. The Steam Summer Sale (full coverage over at Kotaku's Moneysaver) certainly brings out the most competitive deals from Amazon and other digital game sources. I am really looking forward to Amazon deals similar to this all week.
