Rachel Bernstein reports in the Baltimore Business Journal that the National Aquarium in Baltimore and Dunkin’ Donuts have launched a campaign to give customers extra jelly filling.

The campaign, called “One Sweet Deal,” gives Dunkin’ Donuts customers a $5 off admission to the aquarium’s jellyfish exhibit. The coupons can be picked up at the more than 100 Dunkin’ Donut locations in Greater Baltimore.

Visitors to the aquarium will then receive a coupon for a free Dunkin’ Donuts jelly doughnut when they purchase a ticket. The promotion is play on “Jellies Invasion: Oceans Out of Balance,” which opened at the Aquarium on Memorial Day and showcases nine species of jellyfish.

Admission prices to the aquarium range from $14.95 for children to $27.95 for adults, depending on whether visitors wish to visit only the aquarium, or see a dolphin show as well.

The partnership was struck up by the attraction’s public relations firm, MGH, and Comcast Spotlight, which works with the Canton, Mass.-based food chain.

While the attraction often has third-party sponsors, this is the first time in a while that three entities have been integrated, officials with the National Aquarium said. Comcast is a media partner of the National Aquarium and Dunkin’ Donuts and will promote the deal.

Most of the advertising and creative work was done by the Aquarium so there is little additional marketing cost, officials said.

“One Sweet Deal” started Sept. 14 and will go through Nov. 12, during the aquarium’s off-season.
