So it came time for my periodic filter patch bag purchase. I went to my usual source, only to find that they were sold out ATM. Now me, being the impatient person that I am, decided to try another vendor. In my search I saw that Shroom Supply had what I needed for about the same price. Further the shipping costs were reasonable, which is one of my main complaints about a few of the other vendors.
Exactly what I wanted for my upcoming in-vitro project.
I ordered these bags on Wednesday and received them on Saturday. They used USPS Priority shipping that cost me only 5 bucks, and shipped it the next day after I ordered.
