I've begun to actually enjoy Diet Wild Cherry Pepsi. The store nearest me has been running sales for the past few months on six-packs of the 24-oz bottles, and I like to bring them to work. I bought the DWCP the first time because they'd run out of Dr. Pepper, and then they had the DWCP on sale and not the Dr. Pepper (though that is rare; usually the whole Pepsi line is on sale at the same time). Also, it's a good "drink with dinner" soda as well as a sipping soda.
And now, even though I usually prefer Coke to Pepsi, and Dr. Pepper to either, I find I'm enjoying the DWCP for its own sake. I actually am buying it deliberately now.
