Yes. Joining takes under a minute and there is no payment upfront. We visit for a free measurement first, then send a quote at the group's current discount. You only commit when you confirm your quote.

How do the discount tiers work?

Each deal has tiers like "10 confirmed households → 10% off, 20 → 15% off". Only confirmed orders move the tier, so the numbers you see on the page are honest. When Rail Green @ CCK hits a new tier, everyone's price drops together.

What happens if Rail Green @ CCK doesn't reach the minimum?

The deal simply doesn't run — nobody pays anything. We may still quote you individually if you'd like the work done anyway.
