The article about Bulk App Purchasing Support on Windows Store for Business incorrectly states that Windows Store for Business currently lets businesses get volume discounts on apps they purchase.
Apologies as our original blog post (building apps for Windows blog) wording may have caused some confusion.
Currently, bulk purchasing/volume buy (for IT pros) and sell (for devs) is possible today via credit card. However, volume discounts and licensing are NOT yet available. Not included in this release – support for invoicing, volume discounts and organizational in-app purchases.
