How much are you losing in platform fees selling digital products?

I got frustrated watching 10% disappear on every digital sale I made. So I built my own platform.

Launching PayLink on Product Hunt this Tuesday — the simplest way to sell digital products with just a 3% fee and no monthly costs.

Curious from this community — what's the biggest frustration you have with platforms like Gumroad, Etsy or Teachable? What would make you switch?

Would love to hear from anyone selling digital products.
