Hi there, So I sell things on amazon. I have a full domain with shopify setup and rank on amazon. I want to scale with ads. I'm spending a good ammount per day and getting CaC under $10. Do you fellows who sell tangible goods to send facebook ads right to content pages? Amazon listing? Shopify direct? Product pages on your shopify? Looking for ideas for which you do that has the lowest CaC and which you've had success with. Thanks for the input!
