Hey everybody, I have a question and I can't seem to find the answer. With the buy 4 get 3 free promo going on can you wait until after you check in to add the non expiration? If so will you just pay the non expiration for the 4 days or 7 days? I know if you buy the no expiration before you check in you only pay on the 4 days but does that still apply if you wait until check in? Thanks in advance!
