(Radio Iowa) – If you got an ugly Christmas sweater, something in the wrong size or a duplicate item as a gift, ’tis now the season for returns — and the lines at customer service counters are likely long. Margo Riekes, spokeswoman for the Better Business Bureau, offers Iowans a few tips to keep the line moving smoothly. “Be patient because all of the sales employees, especially the first few days after Christmas, are overwhelmed with all the returns,” Riekes says. “If you’re patient, you’re more likely to get some action.”

Standing in line for 45 minutes may try your patience, but she says to consider what it must be like to be the person hearing peoples’ complaints all day long.  “The customer who’s trying to return the gift should always be calm and polite when trying to do so,” Riekes says. “People will be much more willing to help them.” When returning an item, make sure to keep it in the original packaging and in like-new condition.

“Do not take the tags off the things because once the tags are off, it’s probably impossible to return them,” she says. If the gift giver was thinking far enough ahead to enclose a gift receipt in your wrapped box, it will make the process infinitely easier.
