Log on to their website on Saturdays at 9am sharp. Go to the listing you want, and starting at about 9:20, start hitting refresh until the item goes live. At that point, add it to your cart and go to checkout as FAST AS POSSIBLE. Item will remain in stock and is salable to ANYONE until you actually finalise your purchase. This is how you buy a Billet Box. If you want other items...WAIT until you have paid for the box, then go back to buy the other bits and bobs. This is how I bought my rev 3a and boro tank.....which I am likely to sell along with a TON of custom bits.
