Do the early buyers rewards influence if or when you buy a pack?

It would bother me a lot more if the window for the items were preorder only. The biggest game-breaking bugs usually get fixed before the time runs out, so there's less risk of buying a new pack on release day only for the whole thing to be unusable (not to say every bug is fixed, but there's a huge difference to me in "fireworks stopped working" and "the save button stopped working and the game crashes"). I always wait for mods to update anyway, so having a month to purchase is fine with me. None of the items have been unique enough yet to influence my timeline for purchasing a pack.
