I am glad the structural integrity of the raffle automatism is fine. That would have been a nightmare to sort out.
Bob used the "wrong" discount code. Instead of "BLFgiveaway" he used "F710ANDF723" from here. This code is not adding to the giveaway pot and therefore he is not in the list and also not eligible for the giveaway... I'm sorry but those are the rules. So chose your discount codes wisely, in the past a raffle ticket was worth ~$10 on average. (raffle 2-6 had a 50/50 chance of winning)
Discount codes can not be combined as there is only 1 entry field on Exduct.
Mistakes or misunderstandings can always happen. I hope Bob's other issues get resolved as well.
