I got an email from them about this tonight. Sounds like a good deal. I bought 1 case (wouldn't let me buy more than that). Copying their description below...
This is police-trade ammunition that was originally issued to a police department but was never used or even opened.
By purchasing this, you'll receive a full, unopened case of Winchester Ranger RA45TP (45 Auto +P 230 grain T-Series), which includes 10 boxes with 50 rounds each.
Note: Because these cases are unopened, the individual box color and design may vary. Whether you receive a "brown" colored box (as pictured) or a "black" colored box, the ammunition inside is the same.
Description from Manufacturer:

With an unbeatable combination of expansion and penetration enhanced by engineered segments in the patented SXT® design, the T Series can be relied on to deliver consistent stopping power in real world situations. Backed by a comprehensive testing and training program, Winchester T Series is ammunition that always performs at its best—even when things are at their worst.
