Domino's Pixxa has good news for its loyal customers.

To show its online customers some love this Valentine's Day, Domino's is offering two pieces of free, chocolate lava crunch cake with your online order. All you have to do is enter the promotional code "HUG" at checkout.

The free cake is Domino's way of celebrating having reached $1 billion in online sales.
