What is your water source like?
My local tap water is so high in chlorine that I've had it kill off cultures (at least with shiitake and oyster cultures). I started using bottled spring water and things took right off. Ive also had a couple problems with spawn jars and bags getting too wet or too dry and stalling. Never grown P. cubensis so not sure how susceptible it is to these things, but worth being careful about anyway.
You could also try another vendor. The spore depot has free shipping and included freebies, or you could try the free spore ring and make your own syringes. Ebay has decent sources of gourmet/edible cultures and spores if you want to go that way too.
