Have you tried eBay?

Other than a dealership, where can I purchase rubber floor mats with the BMW
logo that the dealership carries.

I've checked www.bavauto.com  and  bmpdesign.com

Thanks!

This eBay link should be better because it has more offerings,

You did not tell us which model you have, so I did my search on the E36,
which is the 3 Series models built in the '90s.
