half baked open source thingy costs $50 a month, im talking about fully custom solution that actually can handle business cases that Shopify can not. such as this product is shipped by itself in a box. that product is actually a combination of the other 3 products. and give accurate shipping quote for an order is 3 boxes 37 pounds each not 1 big 111 pound box. you will need 17 different apps plugged into shopify to get this to work. and yeah you are right, there is a million generic stores that ship apparell and other random crap doesn't have specific inventory and shipping needs and thats Shopify's market. for anything more advanced you need to shell out $2000 per month for Shopify Plus. And let me guess your response to that will be "any serious business can afford that". its like businesses have hand over their cash to Shopify so that can claim to be a serious business. Shopify is a rip-off and clearly abuses their market dominance in the cases like with MailChimp
