Book covers - making the range... a collection?

In my talk with Fred we discussed about how I had approached the book cover brief in a direction that could take the brief a little further than just being book covers. I want to touch on exploring the idea of selling the books alongside complimentary material. I started to do that without really realising the potential behind it (designing chocolate wrappers and bookmarks).

I need a simple, easy way that collects the items together,

my original idea was to use the wrapping paper to wrap up all the items, so maybe a sticker to seal it all up? "Enjoy your night in with a good book and co" (play with that). Or a bag?

I have also thought that I could put small promotional posters on the outside of the shop,just as a small advertisement for the offer inside. It could just be a photograph of the items stacked onto each other?

CUP OF TEA? I could design a selection of mugs??

Testing out varieties for sticker that will hold the items together within the wrapping paper.

I like the idea of having different words, variety of final stickers (the final page of the issuu document).
I feel that using the sentence 'my night in' brands the package too much, I want it to be more of a suggestion rather than purchasing an actual package. There is the option of what you can choose to buy, either way, however much you buy you can 'Enjoy' the contents.
