I've browsed through the themes/apps found in the shopify store and have found just about every feature I'm looking for, except they're all to expensive. I know the trend is now to sell themes/apps with a monthly fee attached to it, but I don't think I should continually pay someone for something they've done once.
I'm also a do it yourself kind of guy, so I'm looking for tutorials on how to code themes and how to code apps that will work on the shopify platform. I want to code my own popups, spin games, shipping rules, etc.
