Hi there! I am not sure which patches you are referring to specifically, but here are 2 you can check out.
Siva: http://www.sivapatch.com/shop You can purchase directly from their website.
Mary's Medicinals Transdermal Patch: http://www.marysmedicinals.com/find-marys-products/ You can use their store locator to see where they're available near you.
Hope that helps!
