Mastercard Day × Drob & Chilli: The Cashback Collaboration

Mastercard Day offers 10% cashback every Tuesday in restaurants, bars and food delivery – both in Bulgaria and abroad. But financial mechanics alone don’t drive behavior. Experiences do.

To turn Mastercard Day from a recurring discount into a recurring ritual, we partnered with Bulgaria’s leading foodie podcast, Drob & Chilli, and built a culinary storytelling trilogy where Tuesday became a reason to explore.

The collaboration unfolded across three immersive audio-video experiences: a spontaneous cross-border road trip to Thessaloniki; a two-part deep dive into fine-dining Bulgarian terroir restaurant ONA; and an episode at the amazing Zornitza Estate. Both ONA and Zornitza are part of the JRE (Jeunes Restaurateurs) network, where Mastercard is a key partner in Bulgaria.

Instead of explaining the offer, the hosts lived it – registering for Mastercard Day, paying exclusively with Mastercard, and naturally embedding the cashback mechanic into real food culture. To reinforce the weekly behavior loop, we also launched Patreon-only “Cashback Episodes” released specifically on Tuesdays.

The campaign delivered strong depth and scale: over 7,900 Spotify plays, 3,600+ consumption hours, and exceptional retention for long-form audio, with up to 59% completion on nearly two-hour episodes.
