I worked at best buy for about 4 months. Their application is online. I dont know if they would be hiring right now because they let some of the holiday people go. Most of the entry level positions, unless you are getting an engineering degree in college, is merchandising, which is what I was in. Basically the truck comes every 2 days and you unload it and put the product out on the floor. The only bad thing is that on sundays you have to come in super early probably 6 or 7 am, during holiday season 4 or 5 am.
If you live in a semi big city, try valet parking. I did that last summer in Atlanta, made minimum 10 an hour but a lot of nights I was push 16-20 an hour. There were a lot of sexy ladies and high rollers too, like ludacris, tyler perry, young jeezy, and president obama. And you will stay in shape
