Let's figure this out a bag of fert at Lowes or Walmart 10-10-10 is $4.42 for 40# bag a bag of groundburnt limestone is 1.40 for 40# , so if we add everything together we are spending $5,82 and gee does that figure 80#.... lso what kind of bargain are you looking for? Whenever you buy something that is prom'd by a celeb or has a picture of a deer on it you will by paying up the yazoo. How do you think these people do that, they go buy fert and lime and put it in their bags and sell it for 28. for 40# hey they even give free shipping.....
