The Calvert Marine Museum Store is again proud to participate in Museum Store Sunday, a global annual shopping event where patrons can shop for uniquely curated gifts while supporting the mission and fundraising efforts of local museums. On these days, CMM members will enjoy 25% off their entire purchase and have the opportunity to increase their discount to 30%, 35%, or 40% off their purchase. One lucky member may even get their entire purchase for FREE! Non-members will receive a 20% discount all day. Some exclusions apply; see Museum Store for details.
