Quick question about Amazon.com?

I bought 2 items from this seller on Amazon. Apparently, this seller is located in Trenton, NJ. I live in Miami, FL and I was wondering what would be the approximate date for my package to arrive? I ordered on May 28th, it shipped on the 30th, and it said the USPS was mailing it to me. How long will I have to wait for the package to arrive? 'cause I'm kind of impatient when it comes to stuff like this... lol.
