From their announcement:
We have been working hard to reduce cost and make the Omni-Stand meet the needs of more gamers. We have decided to split up the packs and sell each component as a single item. This will allow you to purchase just enough to meet your needs withoutbeing restricted by package sizes.
We have also added a discount structure to the store. If you purchase 5 or more of any Omni-Stand item it will add a discount of 10%. At 15 or more of a single item the discount increases to 20%. Now you can outfit you entire fleet for less.
We hope this new pricing structure will help gamers get the most bang for their buck with the Omni-Stand system.
