so i have been looking for pre-pasteurized straw/poo in filter patch bags. it seems that only two vendors carry want i am looking for. high mountain compost has 10 lbs. filter patch bags for $45 after shipping. and mycopath has 10 lbs. for $47. is there any other options for me? this seems a little steep. i had bought some bags a few months ago from one of the vendors (cant remember which one) but i didnt pay near that much...thanks.
