Shop Party City in San Marcos for Birthday Ideas & Supplies

All birthdays are worth celebrating, even milestone birthdays that may seem like a mixed blessing. So if you're planning a party for that special someone, or if you're simply looking for inspiration and fresh birthday ideas, come to Party City Grand Plaza Shopping Center, where birthday supplies are stocked year round and great birthday ideas abound.

Birthday is the core of our party business. Here, at Party City San Marcos, you can find everything and anything related to birthdays. For easy shopping, all birthday supplies are neatly organized by color, type, and theme.

All products we sell are tested for quality and safety before they ever reach our shelves — if they don't pass muster, we simply won't sell them. Best of all, if you're in a hurry, Party City store associates are trained "party experts" who can offer ideas for any birthday celebration, from first to 100th, and direct you to the party essentials.

At Party City Grand Plaza Shopping Center, it starts with over a hundred birthday themes for kids — licensed birthday collections like Mickey Mouse and Disney Princess. The tableware includes plates, napkins, cups, and table cover, and with all that you have the option of purchasing matching invitations, decorations, party favors, and more. Whatever your budget, there's a party plan to fit, and not just with children's birthday, but with first birthday, 30th, 50th, and other milestone birthdays as well.

We offer all kinds of themes, decorations, and favors year round, and at prices you can afford.
