Our philosophy

Never overpay to build again.

We’re two guys from Quebec, fed up with watching material bills blow up and prices swing from one store to the next for no reason. We figured paying a fair price shouldn’t be this complicated. Bâtir à Rabais is the tool we wish we’d had for our own projects. Because every dollar saved on materials is a dollar for your project, your family or your dreams.
