[pct-l] Denatured alcohol/supplies in Vista or Oceanside?

[Will M]

I will be starting my section hike next week and will be flying into San
Diego, staying at my sisters house in Vista.  Does anyone know where I can
get Denatured alcohol near Vista?  What about other trail supplies?

My other option would be to get something at Warner Springs where I plan to
start.  Is there denatured alcohol available there?

Thanks,
