Who are the hardest people to shop for during the holidays?

Americans will spend an average of nine hours trying to pick the perfect gift for the most difficult person to shop for on their list, new research suggests.

According to a survey of 2,000 Americans who celebrate the winter holidays, partners and spouses (21%) were found to be the hardest to get gifts for. That was followed by children (14%), their mom (13%), and even themselves (13%) as the hardest person to impress.

From kids (3.7 each) to partners (2.7) and pets (1.7), along with in-laws (1) and more, the average American plans to give 16 presents throughout the holiday season, though 80% said the current state of the economy is having an impact on how much they’ll spend this year.

When it comes time to purchase gifts, the survey — conducted by Talker Research on behalf of Minted — found that one in five (22%) people will wait until Thanksgiving has passed before they start shopping, while 12% will wait until the week before or even the week of their gift exchange.
