Ordered some stuff over a week ago...get a confirmation for my order all that shit. This was like last thursday. They call me on Wednesday, after I email them asking if my order has been shipped yet. Turns out what I ordered was out of stock, which is why they called me. Found a replacement item, the guy on customer service was really cool. He said it would be shipped out that day so it would be here by Friday (today). I get home, nothin, email them. Turns out it hasnt even shipped yet and I'm leaving for Florida on friday and i wanted the clothes I ordered. Fuck. There is a chance I may be able to get an overnight though so we'll see.
