Lowest price ever on Amazon (without coupons or S&S). This specific product may be available at Tractor Supply Company (TSC) for price comparison. I don’t know if TSC will price match.
NOTE: This is highly concentrated, and makes 85 gallons of the retail Roundup equivalent you find at Lowe’s or Home Depot.
If you object to using Roundup/glyphosate, then this deal is not for you. Take the political/environmental discussion to your own thread, please. This is a deal thread, so keep posts about the deal.
