We used to offer price reduced license packs (e.g. TreeSize Professional - 5 license pack). However as opposed to single licenses, these are site restricted (usage only allowed within one city).
Due to a restructuring of our licenses and a new price scale for single licenses, this type of license has now become obsolete and we are converting existing packages to single licenses which has the advantages of transparent prices, more flexible handling of the individual licenses (whith the same number of keys) and removal of the site restrictions of the packages.
