Two contradicting plan upgrades sat in the cart at 799 and 399 € — no checkout
could resolve which one the customer meant. Choosing another now replaces the
pending one and says so; add-ons still stack, because buying 200 GB as two packs
is a sensible thing to want.
Every price now states net or gross and how often. The cart shows net per line
with "pro Monat" or "einmalig", then subtotal, VAT and gross — and separates
the monthly recurring amount from a one-off traffic top-up sharing the same
cart, because those are two different commitments. The rate is configurable
(CLUPILOT_TAX_PERCENT, 20 % default) since it follows the seller's country.
