Woman Buys a Year's Supply of PSL to Feed Her Addiction

— -- If you’re in Moline, Illinois, you might have some trouble finding a pumpkin spice latte.

“My husband went to three of the stores Saturday night, and they were all three already empty,” Sherry Lynn Gustafson told ABC News. “I was smart to get mine.”

Gustafson, 58, started stockpiling Keurig boxes of her favorite coffee drink after the gas station she got them at would sometimes run out or it would be weak.

So far she’s bought 52 boxes.

“I started wanting it all the time. I thought, ‘I’m tired of waiting,’ so I started getting five or six boxes at a time here or there,” she told ABC News.

She now has three or four cups of the beverage a day.

“Somebody had mentioned something about shelf life, but they’re good until August 2016 so I’m good until next fall when I need my other fix,” she said.

Gustafson’s favorite part of the drink is that it tastes like her favorite fall treat, but with only 35 calories.

“It tastes like pumpkin pie with cream on it. It’s really sweet and pumpkin, and I put my creamer in it myself so it tastes just like pie,” she said. “I can make it a cup at a time and it’s really fresh and smells good.”

This habit has set Gustafson back nearly $260, but she said it’s well worth it.

“We get 5 cents per box off a gallon of gas, so we only paid 76 cents a gallon for gas here after I got my monthly stash,” she explained. “I’m just a normal mom and grandma, but if I like something, at my age I try to make sure that I get it now. I juts figure why not. So what the heck?”
