Wow, I am really puzzled by this promotion - given that is a TGIF `deal'.
Buy any five of this week's releases to receive - on Monday - the unreleased Marilyn show? I would love to - but I have obtained each and every one of this week's shows - as they have been released - before the TGIF promo was offered!
Now I have no trouble trading credits for the Marilyn/Memorable Encounter card - taking it that a promo is just that - a means of enticing you to do something that you have not yet done. Even if I wanted to - and I don't - I can not acquire cards already acquired!
But presumably the Monday arrival of this card, due to this promotion, means that that card will be made available on that day for `sale'? Otherwise an `instant-purchaser-of- wanted-cards-as-soon-as-available' is getting dudded by this promotion! Had I been warned, I would have not made any purchase all week, in order to have access to this (final?) show of Marilyn - my favourite model. A sacrifice for an always-awaited Marilyn card is one that I would have oh-so willingly undertook! Again, she is easily my favourite and to defer `purchase' of all of this week's cards, until the weekend, would have been easily-endured! The reward is extremely high!
I am not sure if there have been similar promotions in the past and how they might have affected members in the same situation that I am in. I am not the only `immediate' purchaser - so expect there might be a few wondering. 
 What will this mean for me and others in this situation?
