CombinePDFs Service 1.0Free
This service will be available in Finder's Services menu and contextual menu if PDF files are selected. It enables you to combine two or more PDF documents by appending or shuffling pages and then to rename the resulting document. Shuffling will add one page from each of the documents to the new document, then proceed to take the next page from each until all pages in all the documents have been added to the new one.
