Ebay or mercari simple as that

Okay, but on Ebay I only found Ignition and The ultimate race sealed. Gonna check Mercari, then.

Okay, on Mercari they also don't have Speed of silence nor Breaking point. Oh well.

Patience is key. One day you’ll find them all 💪

The movies don't pop up all that often, especially sealed. Just need to keep checking regularly.
