The campaign, running through December 31, 2026, features limited-edition packaging across qualifying baking soda products. By purchasing three items and submitting receipts at AHxLEGOLAND.com, consumers unlock a BOGO ticket offer valid at Legoland locations in California, Florida, and New York. Beyond the immediate discount, participants are entered into a grand-prize drawing for a trip that includes round-trip airfare for four, two nights of hotel accommodations, and park admission.

Aaron Greengard, Associate Marketing Director at Arm & Hammer, stated that the collaboration aims to extend the brand's focus on creative play and STEAM experimentation beyond the home. Justin Carter, SVP Managing Director at Merlin Entertainments, noted that the effort bridges the gap between household staples and the immersive, imaginative world of Legoland. Detailed rules and contest information are available on the official campaign website.
