Please note: I will closed on Saturday the 25-Jul-26. For anyone looking for local pickup, I will be able to accomodate pickups Monday through Thursday evenings, just leave a comment when you place the order and let me now when you'd like to drop out to pickup. Orders requiring shipping will still ship out on Monday as usual. Sorry for any inconvenience.
