This is a pre-order item. The Zendikar Rising Collector Booster Box will be available September 25th. Due to production issues any Collector Booster Boxes purchased after 09/16/20 will be delayed to what WotC is calling Wave 2.
12 booster packs of shiny goodness for the Zendikar Rising set. Each pack comes with a slew of foil cards, showcase cards, two dedicated rare slots, and a special slot for cards not found in the regular booster packs! One extra box will be held back to sell the booster packs out of in case you just want a taste of Collector and not an entire box.
Update from WotC: "Initial allocations of Zendikar Rising will be arriving in North American locations in two waves. The first wave will be at the intended launch date of September 25. The second wave will arrive in stores 7 to 10 days after the first wave’s launch. As a result, some locations may experience limited availability until the second wave arrives. Additionally, Zendikar Rising Bundles in North America and the Asia-Pacific region will be delayed and will arrive in stores as soon as possible, though they are unlikely to be available at launch."
