People are selling empty Moderna vaccine bottles on eBay. Current "Buy it Now" prices range from $22 to $75. One bottle sold there for $282 at auction but that was back in January.

Curiously, there haven't been any listings for Pfizer or J&J COVID-19 vaccine packaging.
Also available, empty 10 vial Moderna boxes for a Buy It Now price of $50:
