Why there is nothing here
Most promotions in this industry are deposit bonuses in costume: the headline is a number, the substance is a turnover requirement, and the terms arrive after you have qualified. We would rather have no promotion than one that needs a lawyer to explain.
What we would publish if we ran one
The value in numbers, the turnover multiple, the expiry, the maximum withdrawal attributable to it, and whether it can be withdrawn at all — all on the offer page before you accept, not in a document after.
