Any specific store? Not unless you live very close to me. The best local stores for fertilizers aren't usually large chains.
The best fertilizers include Worm Castings, Maxicrop soluble powder, Blood Meal, Kelp Meal, Bone Meals, Bat & Seabird Guanos, Fish Emulsion/Hydrolyzed Fish and Palm Bunch Ash. Most of these are solids that need to be either mixed into the soil or made into teas for manual fertilizations. The best premixed liquid ferts are teas made from these fertilizers. They're not as fresh but easier to use.
