Shoprite usually has it. I haven't checked this year. You could call.
If you go to ShopRite, try the store in either Livingston or Essex Green. They have the largest selection of Kosher for Passover merchandise.
Here are the Shoprite Livingston and Essex Green telephone numbers. Millburn doesn't have any left.
Livingston - 973-740-2004
Essex Green - 973-736-9374

So far can only find the toasted onion flavored stuff. Any ideas where to find PLAIN gluten-free matzo?
