I have a 3-for-2 campaign (BuyQuantityGetFreeItems)  within a category. 

I buy quantity 2 of item A and 1 quantity B, and end up getting B for free. I also add item C that has no discount to the order.

The problem occurs when retrieving skuIds connected to promotion:

// fetching all active promotions on orderForm
foreach (var promotion in orderForm.Promotions)
{
     var skuIds = promotion.Entries.Select(e => e.EntryCode).ToList();
}

Here I would expect to get both item A and B, but I only get item B.

Both A and B are active on the promotion, and B would not have been free had I not bought 2 of item A.

Am I missing something here, or is this a bug?
