You're very lucky. My local library has had to cut the hours they're open, due to funding cuts from the local government. (My take is that the politicians feel that the more ignorant the public is, the better is is for politicians.) Definitely no $ available for Mosaic boxes here.
To my amazement and delight, we buy almost everything on Mosaic and a fair bit of Bear Family too. Great and expensive library, beloved here in the Peoples Republic of Portland.
