Totally agree with the plants don't care what name is on the bag. These fertilizer distributors all buy their bulk product from the same small group of manufacturers and then mix it up just a bit differently.
For a dry fert Maxi is still boutique priced between $8-$12 pound. If you buy from big agro distributers like Growmore, Southern AG, Jack's, Masterblend you can come in at $2-$3. It's not a bad option for small growers to buy big bags. It only takes a few minutes to break down a big bag into smaller ziplocks and then toss those into a 5 gallon bucket with an airtight lid. Then your all set for a while and can pull a baggie or two as needed.
