I doubt its the local garage guy killing LFS business. BRS, Marine Depot, Salty Supply, Etc kill local shops, along with the different shops and their owners acting like nuts. Poisoning each others tanks, turning in local reefers, giving bad advice and overpricing everything closes shops. I'm down to one store that I support and give 99% of my business. If they were to ever close, I'd go all online or just tear it down... I don't trust anyone else and probably never will...
Also, if anyone finds out a shop or individual is turning in locals feel free to burn them, I sure as heck will.
