Hi Khan,

The coupon code does exist for the save PO in OrderFormEx.

SELECT * FROM OrderFormEx where Epi_CouponCodes  IS NOT NULL 

So we can retrieve the PO + Coupon Codes with this way:

var pos = _orderRepository.Load<IPurchaseOrder>(CustomerContext.Current.CurrentContactId);
var couponsWithOrders = new Dictionary<string, string>();
foreach (var po in pos)
{
    List<string> couponList = new List<string>();
    foreach (var form in po.Forms)
    {
          couponList.AddRange(form.CouponCodes);
     }
    couponsWithOrders.Add(po.OrderNumber, string.Join(",", couponList.Select(x=>x)?.ToList()));
}

I am quite sure this is one of the recipe in my second book that you purchased :)

It was the very custom thing I guess,
IContentLoader, IPromotionService and PromotionInformationRepository helped, but I had to record Coupon Usages my self
