Kroger sells the Good 2 Grow Singles for $21.59. Buy one Single for $2.59 and get a free 6-pack refill priced at $3.49 at Kroger. Final price $2.59 for both the single and the 6-pack refill.
The Good To Grow Single Bottles are $1.97 at Walmart. I don’t have the price for the refills, but his may be a better deal at Walmart.
