Between the school holiday events, the sporting events, the birthday parties, getting dinner on the table, managing your own to-do list and maybe even trying to squeeze in some time for a workout or a girls' night out, the last thing you want to do is spend hours at the mall shopping for everyone on your gift list this holiday season. We get it. In an effort to make this year's gift buying the most efficient yet, we've rounded up the hottest gifts for little kids, big kids, teenagers, parents, and grandparents — all from Best Buy. One-stop shopping, anyone? That's what we thought.
