Discuss time | Shop ideas

Hello from Poland, since my last post I have learned a few new things to code with, such as TypeScript/NestJs and EcommerceJs. Also now I am studying internet marketing and want to make online shop to combine these skills.

Have you any ideas which shop will be useful for next months? Share them in comments, I will be glad to discuss your ideas with mine and I think in future, when I chose a shop idea, I will make posts related to this shop's progress. Thanks
