hi i have amended the custom ecommerce provider to create a .csv of every transaction that goes through the site. this csv then goes into our accounting system. i have been made aware that the system has failed when orders have gone in with discounts applied. so i need to do a check to see if a discount is in the basket:

foreach (CMS.Ecommerce.ShoppingCartItemInfo cartItem in cart.CartItems)
{
//how can i check if this is a discount?????
if (!((ShoppingCartItemInfo)cartItem) == discount)
{
}
}
thanks for any help!

phil
