Best on Amazon under $5!

I didn't really know where to put this, so I just threw it here, please redirect me if this isn't the right spot.  I just got a 5$ amazon card from bing, and I was just wondering what you guys think the best tech item that I could buy on amazon for 5$ less.  It has to be free shipping, or the shipping plus the item has to be 5$ or under!  Let's see what you guys think.  Don't ask what I am looking for because I really don't care, whatever you want to put.


Cables cables cables, maybe get a USB drive or something 

get a phone case

get some thumb tacks, thats probably the only thing you can buy with a 5$ gift card
