Can I have an "extra item" which is sell in other gig?

Hi there! I have a question.

Currently I have 3 gig, one of the is very successful, but the other two are not. All the same are related with Crowdfunding advertising.

I want to know if it is correct (not against any rule or TOS) to include what I sell in the not so successful gigs, in the one who is more profitable for me, as extra ítems. If this gives me better results, I will delete this 2 gigs.

Thanks for your time 🙂
