Is it possible for this scenario to happen? Buyer places an order on eBay without paying. GetSellerTransactions returns that order with unpaid status and no containing order. Buyer places additional order, resulting in a combined order. GetSellerTransactions returns the first and second order with containing order info. On my end I would see first order with 1 order item and then an order containing 1 order items, unless I do some checking on my existing orders.
