Just a heads up, both Amazon and Walmart are selling M1 (most grades) for $22-$23 per jug right now and there’s a $12 mail-in rebate for up to two jugs per household. I can’t link due to Kinja, but try pasting https://apfco.com/secure/r8235w/… for the actual form, which the stores might not have (Neither store is listed as “official” but countless people online say it’s 100% successful). Hat tip to Slickdeals on this.
