I had the same Trello boards experience, only my products were collections of class activity ideas and templates. I ended up making them freebies after they didn't sell well. I also have a repetitive freebie, my workbook about designing your first college course. But I haven't tied it to a new paid product yet, other than my Creative Confidence consult calls. I need to put more thought and attention to adding a paid product to that particular freebie. Glad to hear your business is going so well!!
Thanks so much for sharing! It definitely took me a while to figure out what would work for my audience! Definitely keep creating, and listening, and iterating!
