Found this article while surfing the web, from page to page, the blog of Kirin Notebook. Very handy for my own business, especially the pricing. I’ll take it as a rule of thumb. Thanks Kirin!
And another blog article focuses more on cutting costs by rethinking the items you use and getting more efficient. I like the idea that unless a similar product is not cost covering or does not look worth it’s value in comparison with the other existing items, then to keep it ‘in development’.
Going further down the road with marketing and advertising goes this article on Etsy, not so fresh anymore, but still insightful.
