This is really irritating me. People suggesting products to her - ‘great idea, we’ll put it in discussions’. What discussions? With whom? You’re using a white label on-demand printing reseller and are subsequently limited by their extremely restricted product range. They’re not going to add to their catalogue to support your (likely wildly exaggerated) order volume, so who exactly are these ‘discussions’ with?
It would take less than 24 hours to register, fully populate and launch the store she currently has, and that includes all the ‘designs’, if you can call them that (speaking as a professional designer). The idea that this is something she’s been working her socks off on is utterly farcical.
