I've just had a reminder from Astronomers without Borders that they sell eclipse glasses. However there is a minimum quantity of ten. If you have family, neighbors, school, scouts, etc. group, then this is for you. The larger the quantity, the lower the price.
If you look after the glasses, you can use them for another solar eclipse or for sunspot viewing. (Don't use them if the filters get scratched or damaged.)
Here is their web page - and there's a sale on! By the way, the profits go to support astronomy programs worldwide.
