Now that I am beginning to think about starting seeds and my medium is soilless mix like Miracle-Gro and its equivalent. I like the largest size bag; how is the supply? Mostly I purchase at big box stores since it is usually cheaper there and plentiful for the most part.

Anybody notice supply chain problems? I have a small left over bag for seed starting but need to replenish our raised beds and need 5 or 6 bags.
