As long as what you are buying is 3.8 lb per gallon 2,4-D amine it is all the same. The difference between TSC and JD is that JD is charging you homeowners price. A licensed applicator buying it by the drum or 275 gallon mini bulk along with several tons of fertilizer per year pays a different price.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
Benjamin Franklin 1775
Sell not virtue to purchase wealth, nor Liberty to purchase power.
Benjamin Franklin Poor Richard's Almanac1738
