Pack-in material

Since the very beginning of Transformers, Hasbro has been including pack-in material with toys. The first example was the toy catalog, simply advertising all the available Transformers. But soon these were accompanied with mail-order flyers for additional exclusive toys, then mini-comics, contests, and more. In more recent years, CD-ROMs and DVDs have come into vogue, containing cartoon episodes and various interactive features, though more "low-tech" items like stickers and collector cards are still common.
Catalogs
Hasbro has often used pack-in catalogs to advertise their range of available toys. In the days of Generation 1, they were expansive affairs that would document an entire year's worth of product. In more recent lines, they tend to have a more limited focus, though they do occasionally branch out into advertising for other toylines.
Mail-order flyers
In Generation 1, Hasbro sold certain toys exclusively via mail-order flyers included with retail toys. Reflector, the Omnibots, and the Powerdashers are probably the most well-known of these. Mail-order flyers were also used to sell a few other Transformers that had been discontinued from the main line. Membership in the S.T.A.R.S. fanclub was also available, and many flyers contained story material related to this that constituted a distinct micro-continuity.
