Burns Park Loop

I jogged about twenty percent of the time to complete the Burns Park Loop at lunchtime today in 1:37:49.
I bought a 24-tube case of Gu this morning for $12.95. Before I ran, I drove to a sporting-goods store to buy some golf balls. While there, I decided to pick up some Gu. Individual tubes went for $1.35, but they also had a few 24-tube cases with no price marked on them or anywhere nearby. I deliberated for about nine seconds before I uncharacteristically said to myself, fuck it, motherfucker, you know you can afford to not be so fucking cheap all the time. Just buy a fucking case, so what if it's thirty bucks? I was really kind of proud of myself, so you can imagine my absolute delight when, as a second thought nearly three hours after I walked out of the store, I reached in my living-room trash can for the receipt to learn that I bought 24 goddamn tubes of Mandarin Orange Gu for $12.95.
I'm pretty sure someone at the store fucked up, so I'm going back for more before they figure it out. I wonder what the shelf life of Gu is.
