No price guarantee is currently offered by Servik.
This page describes a design only: a shop-confirmed quote, frozen at confirmation, checked against the price actually paid. No refund, honored price, or other outcome is promised. Before any guarantee could go live, two things must exist first: a support answer (who resolves issues when a booking or quote goes wrong) and shop acceptance volume. Neither exists yet.
Check the design evaluation for a completed booking: enter its booking id. The answer will still say not live — the evaluation only shows what the design would look at (frozen quote vs price actually paid).
