Yeah prices have definitely changed a lot over the last several years. A big reason is import restrictions and supply issues. Many corals like hammers and torches used to come in large amounts from places like Indonesia, but when exports were shut down for a while it created a shortage. At the same time demand in the hobby kept growing. Add in shipping costs, farmed coral pricing, and social media hype around certain strains and the prices went way up. Some have come down a bit recently, but they’re still way higher than they were years ago
