I've been looking at old Compass's from Oasis. They run a buy one get one 50% off it seems on first day. Does anyone know what the cost is on the 1st package and, if you purchased a package before the cruise, can you cancel and get the deal (if it's a savings)? Looks like now they have a $4 off per day but wonder if they also offer and increased discount before sales end on Jan 30?
