All cd's are shipped Royal Mail 2nd Class as standard unless you upgrade for 1st Class.
All stock is despatched within 24 hours, on some occasions on the same day.
If you buy 2 and get a 3rd free you will need to purchase both paid items at first class to receive all 3 sent first class post. All 3 would be sent together in the carded mailer (including all tracklists etc).
