around here, the generic 41% glyphosate is $90 for 2.5 gallons and $40 for one gallon. roundup is so much higher, i don't see why anyone would want to use it.
More than likely what you bought for $14.00 at Kmart is the ready to use RoundUp with water already added. A gallon of concentrate will be much higher.
No way, Tex. It was the concentrate. Their ready mix was $7.95 gal. ;Go figure. My gal. will make 10 gal. of mixed. That much of their readymix would cost $80.00.
