They are affiliating shopify. There price, cost calculation totally unethical.
SSL $100? SSL $9 from namecheap even it is free if you use vps.
However, Shopify for short term business and perfect for beginner's. But, woocommerce for long term business and perfect for who already pass beginners phase.
I still don't understand why you guys are focusing just on shopify or Woocommerce. Why not use free one , such as FB shop or Tictail?? You can save your money for hosting shop to marketing budget
