I have done business with Super Cellars on numberous occasions, and have never once had a problem. I always request that my order be shipped on a Monday, and the longest it has ever taken to arrive is that Saturday (last order was recieved on Thursday, and this is ground - coast to coast).
The packing Super Cellars uses is fine - they are cardboard wine shippers with added foam "peanuts" for added packing. The cardboard inserts are made for wine shipping, and of all my shipments from these guys I have yet to have any damage whatsoever (always ground service, from NJ to CA).
In short, they are a fine retailer with good prices and reasonable shipping when ordering a case or more.
I have no affiliation with Super Cellars, just a satisfied customer.
