I have a new job, I want to put in my notice and work the last 2 weeks, but others say go ahead and quit?

The new job is at a supermarket a half mile closer to my house, it is a mile walk to and from my house, and it pays 4 dollars more per hour than my current job. Plus it's just stocking and not having to stock and run register at the same time like I currently do with Dollar General. But, at the same time I still wanna work my 2 weeks to be fair and give them common courtesy
