I tried WooCommerce. I am not a fan. A lot of plugins are free but you have to pay if you want the advanced features.

I have been working with PrestaShop since version 1.2. The current stable version is 8.1. PrestaShop offers a lot of features. You should give it a try (for free).

Hvorfor dog spotte de gode bøger? Var det ikke bedre at rose dem?

Jeg synes ikke lige, jeg kunne finde noget om en firmakonto til 105 kroner i kvartalet. Har du et link?

You did not mention awk.
