Dang, $450 plus another $120 is a lot to lose, but was the kit really ALL junk or just a couple things? A small tank and a bad thermometer still work as backups, and the lamp can be swapped for a cheap bulb instead of buying a whole new setup. Moldy substrate after 10 days sounds more like the tank was too wet or there was no airflow, not that the dirt itself was trash. Half the battle with these expos is knowing that the guy selling bundles gets a cut, so yeah do your research next time, but calling it wasted money when you got a working setup out of it is a bit much. Sounds like you learned the lesson cheap, honestly, some people lose a whole animal over stuff like this.
