Shipping & handling buddy, that's where your profits will be! Let people think they're getting a good deal then get all your profits in S&H. Put the item in a bag, lick a $1.00 stamp put it in the mail box and charge $25.00! This is what I suggest...
...by the way did I mention I'm 30 minutes away and will pick my stuff up. I'll bring you a double-double, we can forget shipping and handling right?
