Who hunted CartMargin?
CartMargin was hunted by Henry Palancar. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it. Hunters typically write the first comment explaining why a product is worth attention, and their followers are notified the moment they post. Around 79% of featured launches on Product Hunt are self-hunted by their makers, but a well-known hunter still acts as a signal of quality to the rest of the community.

I made CartMargin to help sellers check a promotion before running it. Enter your own costs and compare discount assumptions. Results are contribution, not net profit or a prediction of sales.
