Payment Director - If certain product is in cart, then only allow COD payment method

In this Payment Director example, we only want to allow COD if the cart contains an IPod.

Set up a variable to calculate the condition, and then suppress all options except COD if the condition is not met.  For example, let’s say that you generally offer two payment methods – COD, and Credit Card (e.g. Authorize.net).  However, if the cart contains an IPod, then you only want to offer COD:

Product SKU(s)

                Items.Any( "12345, 56789, 55555".Contains(Product.Sku) )

Product Name

                Items.Any( Product.Name.StartsWith("iPod nano") )
