No way to tell if VAT is included in prices from marketplace sellers

Takealot is great but there is one really annoying problem. It is impossible for a buyer to determine before purchasing something, whether a marketplace seller is VAT-registered or not. If the buyer is VAT-registered this makes a big difference because they can claim the VAT back. Which means that they don't actually know what price items are being offered at until the deal has already been done. If takealot listens, perhaps they can comment. I've raised this before through their own help lines and been met with deafening silence.
