Don't know if this was posted already but newegg keeps owning when it comes to pre-orders Rage $54.99. Use Promo code EMCYTZT725 to knock it down to $46.11. Includes Free Shipping.
Thanks for the info, OP. I was looking for a copy for $40 or so. I'm very happy that Newegg is selling preorders for sub $50, especially since it seems like the era of the $60 PC game being common is nigh.
Unless you have Amazon credit, this is the better deal as you get the discount up front. If I were buying this at Florida retail it's essentially a $39.99 game before tax.
