Outsized Item Shipping (don't want price showing)

Hello,

How can I NOT get the price showing (not even 0 €) on one manual shipping method -- for outsized items that have no "standard" corresponding price?

See "Hors Gabarit" in attached picture. It appears for items for which I put a 999kg weight. For testing purposes I put the 999€ shipping cost otherwise I get "livraison gratuite" (free shipping) appear.

(any other ideas on how to handle such a situation are welcome)

Thanks

Stephan

Thank you for your answer Nicolas but the problem is not so straight forward. (as with most of those head-scratching shipping rules)

I am using the Manual shipping module in which I created shipping rules based on the French Colissimo system which is based on WEIGHT.
I've got about 70 rules and it is working well as I have a weight for every product but NO dimensions as these are not standardised [varying physical shipping size for a same product].
However, the Colissimo system [as well as fast courriers] has SIZE restrictions [Les dimensions maximales sont telles que : L+l+h=150cm avec L=100cm] and an OVERSIZE acceptance limit [Dimensions maximales : 150cm < L+l+h ≤ 200 cm et/ou L > 100cm].

I only have a minute quantity of oversized products and I would have wished to avoid giving dimensions to ALL my products .

But, as far as I can figure out, I cannot avoid displaying the price or the "Livraison Gratuite" without a conditional rule for those items identified as oversized. I would have wished something like "sur devis" to appear instead.

I think I will live with the system as is and adapt my messages for the time being.

Thanks again.

[any Colissimo shipping module in the works?]
