Yes. You can "bundle" several decks, images, fonts, or files and sell them as a package at a single price. You can also mix and match, so if you have a file that you want to bundle with your decks, you can do that too.

You can continue to sell each item of a bundle individually, however, if you want to prevent members of a bundle from showing up in the store listing, simply "private publish" the item. Private publishing parts of a bundle make sense if you think the individual pieces don't stand alone but make a great offering collectively.
