What VAT is applied to OSRA Swag?

I just ordered the Lyrical swag. And I can’t figure out what VAT is applied to it. The website does unforunately not help with figuring it out.

Subtotal (5 items) €42.93
Standard Shipping €9.46
Discount - €8.60
Sales Tax €7.54
Total €51.33

VAT in Czech republic is 21% (from the goods price + shipping). I can’t combine these numbers in any way to get to a 21% VAT.
