If you’re about to sign a two-year contract for a new activation or upgrade from Fido, there’s a promo right now from the company which offers up a free Google Cardboard viewer, if you sign up in-store.

Google Cardboard is the technology giant’s affordable virtual reality viewer, which just launched in Canada last month to purchase for $20.

The fine print reads it’s a “limited-time offer, while quantities last,” only available with new activations or upgrades on 2-year Fido Pulse Plans.
