1) you will probably get a seizure letter if it was seized at all. i have had packages sent two days from each other and received them two weeks apart.
the only other scenario would be a controlled delivery. i doubt you should worry about that.
a seizure letter could take 30-90days to arrive
2) the reason why you wouldnt get a controlled delivery is dependent upon the size of the order imo. if it is obvious you are getting more gear than 1 person would use(trafficking) then you could be questionable. i rarely hear of any controlled deliveries.
good luck
