I have seen an occasional pallet of MGOCPM at Wal Mart, Martinez. It is not always there, though.
Glad you found some. Each Ace is independently operated, so stock may vary. Worth checking out more than one, if there are several nearby (I can think of at least 4 near enough for me to drive to)
Safe-T-Sorb, available through Tractor Supply (Dixon, a bit of a trip) or Turface, available through irrigation stores such as John Deere or Ewing Irrigation.
