Kevin Andresen and his dad, Jeff, on Thursday faced an oft feared post-Christmas retail challenge: exchanging an item without having the receipt.

"I got one of these and it didn't work so I had to exchange it," Kevin Andresen said, holding up his new micro USB phone charger.

Using a credit card number, an employee at Boulder's Best Buy, 1740 30th St., was able to quickly verify the broken charger was purchased through the company and replace it in no time, taking the sting out of the day-after-Christmas chore for the father-son duo.

"It was pretty simple, which is good," Jeff Andresen said. "No complications. No paperwork."

The Andresens were part of a steady stream of people that queued up at the Best Buy customer service desk Thursday, but Chris Rute, general manager at the store, said there was much more going on at the electronics purveyor than exchanges and returns.

"People are coming in and using their gift cards and still enjoying the shopping season," Rute said. "It's just another busy day."

At the nearby Twenty Ninth Street mall on Thursday, parking spaces in the covered garage were a hot commodity as people took advantage of the unseasonably warm day to address their post-holiday shopping needs.

'Not as crazy as I thought'

Longmont resident Marlene Guerrero enjoyed some drinks from Starbucks on a bench at the mall with her mom, Carrie Baken, daughter, Carina Watkins, and daughter's friend, Gabby Casey, as they took a break from the stores.

Guerrero said she had some clothing items she wanted to return or exchange at White House Black Market, but her primary reason for stopping by Twenty Ninth Street was to allow Carina the chance to use a gift card. For $170, the 16-year-old purchased a pair of new sunglasses, complete with high-contrast "happy" lenses.

Despite the number of cars in the parking lot, Guerrero said she thought it was relatively quiet for the day after Christmas.

"It's not as crazy as I thought it would be," she said. "I'm happy, I guess, but I wonder if that's symptomatic of the economy or if people just spent so much money on Christmas they don't have any left."

Inside recent Twenty Ninth Street addition H&M, it was plenty busy around 3 p.m., with a line more than 20 shoppers deep leading up to the popular apparel retailer's checkout area.

H&M was advertising a 75-percent-off sale, but that has been going on for a few weeks, according to department manager Ashleigh Jones. She said the store had seen a good number of returns after opening at 8 a.m.

'I like to hit the sales'

Back out on the sidewalk, Windsor resident Allison Miller adjusted a blanket covering her 18-month-old son, Andrew, in his stroller.

After grabbing lunch with some friends at Pasta Jay's, Miller said she decided to stop by the mall because of the sunshine and the prospect of some post-Christmas deals.

"I bought some cards for next year, actually," Miller said of a purchase she made for 50 percent off at stationary store Papyrus. "I probably wouldn't buy cards there at full price, but I love their stuff."

Miller said she doesn't mark the day after Christmas down on her shopping calendar, but when the situation is right it can make for a good experience.

"I don't make it a priority, but there are usually good deals, so I like to hit the sales," she said.
