Williams was also surprised her roommate was the one chosen.
"She wasn't very excited at all [during the interview]," Williams said, "and I was hopping around all excited."
Nevertheless, when the taping started more than 13 hours after Mitchell and Williams arrived to wait in line, Mitchell was one of the first four people to "come on down!" to Bidder's Row.
"I couldn't believe it," Mitchell said. "It seemed like it wasn't real."
But was Williams jealous that it was Mitchell who got chosen?
"I told her before the show, 'If you get up there, I'm not going to help you,' " Williams said. "So I did kind of give her a glare [when she got called]. I did try to help her, though. I didn't want to strand her."
Once she was chosen, Mitchell looked to Williams for help on how to bid, but the studio noise made holding up fingers the only way Williams could communicate with her roommate.
"You can't hear anything. It's so loud in that studio," Mitchell said. "You can't think. I really didn't say much. I was really nervous."
After ordering tickets last semester, Williams said she started paying more attention to the prices when she watched the show. Similar prizes are used every couple of weeks, she said, which helped her communicate good advice to her roommate.
Mitchell made the right pick on her fourth chance to bid, using the old trick of bidding one dollar more than the highest bidder and winning the baby furniture.
Although she wanted to play the popular "Plinko" because she could win cash, the player before her got that one. The pricing game she did play, "Coming or Going," Mitchell described as "the easiest game you could play" because there is a 50 percent chance of winning. And win she did, earning the baby grand piano.
Then it was time for Mitchell to spin the big wheel in the second Showcase Showdown.
"It was really heavy," Mitchell said. "It took like all my energy to spin it."
The first spin only yielded her five cents, but Mitchell hit it big the second time around, landing on 85 cents for the No. 1 slot in the showcases, which gave her the option of bidding on the first showcase or passing it.
Mitchell passed on the first one, which included furniture and a trip to China, and instead got to bid on the computer, global positioning system, lawn mower and camper. Getting the signal from Williams, Mitchell placed her bid, winning after she was about $1,000 off.
"I was looking for a car, but a car didn't come up in any of them," Mitchell said. "I guess I was just excited to be up there. I mean, what am I going to do with a riding lawn mower?"
From there, all Mitchell had to do was sign some paperwork, and the prizes were hers. The show is shipping all her winnings to her parents' home in Indiana, Pa.
As for what she'll do with the prizes, Mitchell has already decided to give the computer and printer to her sister, and her parents are contemplating keeping the camper.
And as for the rest: "I'm going to sell as much as I can sell," she said.
