Hi guys, I use adtech 820 for most of my infusions, I pick them up from a close by dealer at $130 for a gallon (hardener included) am I paying too much? oh by the way I am in so cal. if anyone orders it online for cheaper please let me know…
thank you

I have bought a few gallons of that same resin/hardner, for approximately the same price in Ohio.
