Recently we have found the bug related to products price in Oscommerce MS 2.2 and its earlier versions.

Bug allows to buy any product with zero price. Bug is reproduced at live Oscommerce demo (http://demo.oscommerce.com/).

Please check out http://demo.oscommerce.com/?currency=usd and look at the price which becomes zero. This things allows customers to purchase products with zero price instead of the set for this product.

The bug is critical for those store owners who sell digital (downloadable) products, becuase customers will be able to download a product buy paying a zero amount of money.

You can check out your store. Simply add ?currency=usd to any store URL.
