EBay question...can I cancel this item and not sell it to a certain person?

Okay so someone bought the iPod on my eBay auction.

Person has 0 feedback whatsoever, made an account last night. Also, the shipping address looks REALLY freaking sketchy…it barely makes sense. it says like “2 right” under the street number and name and it just looks…weird.

Can I cancel this and NOT sell it to this person? I don’t want to risk getting scammed by someone who looks like a sketchball. I want to know so I can cancel it before they pay me…
