ProductVariantAttributeValueCollection pvaValues = shoppingCartItem.Attributes; [here the count comes 0]{case1}
}
public string GetAttributeDescription(ShoppingCartItem shoppingCartItem)
{
string result = string.Empty;
ProductVariant productVariant = shoppingCartItem.ProductVariant;
if (productVariant != null)
