The Craft is a very personal choice and what path you choose to follow. It kind of sounds like you have chosen a solitary path for the time being. But as you evolve and grow it doesn't mean that path can't change. And not sure what you mean by supplies. Think about our ancestors why did they use candles? Partly because it's the only source of light they had. While I use candles in all of my rituals you don't have to have a specific type or size and white candles can be used for any color.
Magick is energy and energy is inside of you. Some people consider peacock feathers to be very unlucky and should not be used in rituas but I use then because they were part of my wedding decorations and that much love and positive energy infused into them are great for my rituals and for smudging.
Look in your kitchen cupboard cinnamon, basil, oregano, ect can all be used. Rocks found outside charged correctly can be used. Our ancestors didn't have shops or ways to purchase things for the Craft. They found ways to use what they had for their intent and purpose. You can also.
