Menards has Milorganite Lawn Fertilizer on sale for $8.88 after mail-in rebate good through 3/28/20. $9.98 without mail-in rebate (which is still a great price)
If you don't have a Menards by you or they don't sell Milorganite at your local Menards (like in my situation)
Lowe's price matched it to $9.98 (the price before the mail-in rebate) for me. Price at Lowe's is currently $15.98. Mileage may vary by location/ manager not willing to. Typically Lowe's out by me price match without allot of scrutiny.
