Hello paintscam, thank you for your review. I'm so sorry to hear about your experience with the amount of paint in our 5-gallon container. I understand your frustration, and this is not the experience we want our customers to have. Our deep base requires colorants, so there is room left in the container to ensure there is enough space for the appropriate colorants to be added for the color chosen. Other colors tinted to a different base like our Ultra Pure White base typically don't require as much colorant, so less space is needed in the container and the container may be fuller compared to the deep base. Customer satisfaction is important to us, and we appreciate your feedback. Please feel free to reach out to our Customer Care team directly for further assistance. Our team is happy to help you! -Joni
