Requesting advice from those who have experience selling journal bundles through Amazon

New here! I’ve created a POD 6-month journal with guided prompts and additional content that I intend to sell through Amazon. Does anyone have experience doing this? I would love to package journal stickers with it – is there a way to do that?

I see other journals for sale with sticker packs included. I’m wondering if those are ‘big businesses’ who do the order fulfillment themselves. I don’t have the ability to fulfill orders myself so need it to be taken care of by Amazon (which is why I don’t plan on selling via other sites).

I also see most journals have a linen or faux leather cover. I did not see either as an option for the POD section. Is there a way to get one of those as my cover?

Truly appreciate your insights. Thank you!
