The mycokerewards.com promotion has turned out to be very popular among soda drinkers — so popular in fact that the 800-point award, redeemable for 5,000 Delta SkyMiles, is now “sold out.”

Who says miles are losing their appeal?

In case you’re wondering, a 20-oz. Diet Coke is worth 3 Coke points and there’s still time for you to drink up the 4,000 points necessary for the 25,000 SkyMiles reward (Let’s see, 4,000 divided by three — that’s approximately 1,330 bottles of soda — better get drinking). Of course if you’re not a heavy drinker, a single-visit Delta Crown Room pass is available for only 200 points.
