Golden Oyster: what do the growing supplies cost?

Golden Oyster supplies are sold in 6 product categories (grow kits & fruiting blocks, sawdust spawn, plug spawn, spawn (medium not stated), liquid culture, agar & lab) across 2 US vendors — 17 listings tracked, 11 in stock, updated September 4, 2026. Prices below are grouped by category because a grow kit, a bag of spawn and a culture syringe are different products; comparing them against each other would be misleading.
