I ordered a used kit from Guitar Center 6 days ago, and it's still sitting in the store. ERRRRRRRR. I called them today and they said it would be shipped today, they were waiting on shipping boxes. I figured a big outfit like GC would ship right away. Has anyone else experienced this slacker behavior from a big store? I'm rather shocked, and kind of bummed out that it's not been shipped yet. Or does it make a difference that it's a used kit?
