Better than the "Name Brands"

I have used this weed killer in the past and was quite happy with it, but this year they did not have it yet in store when I stopped to pick it up to spray my yard so I tried one of the "Big Name Brands" it's twice the price so I figured it would work even better and I didn't want to take the time to order this online and wait to have it delivered. Well I was wrong! It didn't work as well and I ended up ordering this online anyway and re-spraying my lawn I learned my lesson and even if I have to order it and wait for it to be delivered I will next time. Nearly half the price and works better than the "Big Name Brand" you see advertised on TV.

Sure, I could have just gone to the big HD or L. Even the Walmart store had this available. But sometimes it is much cheaper online, and I don't think Walmart matches their own in-store with their online prices. Regardless, I had other yard products to order, so saving $5 or more on this was easy. Came in perfect condition and got rid of my yard's weeds.

Good stuff for the Charlotte NC area

I keep buying this product. I live in the Charlotte NC area and I think I only have a few types of weeds, but they are extremely healthy year-round. I think this Spectracide is my favorite. Over the years I have switched during the year to keep the weeds from getting accustomed to a certain poison. But this stuff seems to produce the best results for me. For $8, I can use a 1 gallon tank-sprayer at least 8 times (I think). My neighbor has his yard sprayed by Top Turf for $35 per month. Of course this is also fertilizer, but I have started the Scott's 4-season program in the Fall. I hope this resolves my weed issues and it's about 25% as much as my neighbors.
