Hi Confusedmonky13,
Sorry I'm a bit confused about your question. So if my answer is not right to the point please let me know and kindly clarify your question so we can help you out accordingly :)
If you are planning to start your own website you can easily sell the products featured in the links you mentioned. Also, an ecommerce platform should not be a concern if you are selling on your own website or store since your own website or webstore will be a stand alone site.
This is actually one of the many advantages of selling through your own site there is no limit to the number or kinds of products you can sell. Plus no fees to think about!
I suggest checking out our very own SaleHoo Stores, Link hidden: Login to view and hopefully you can start your own website/store real soon :)
Hope this helps!
