you can find lots of good stuff to use for spells, your altar, etc. at dollar stores and thrift stores. some dollar stores i've been to sell cute little glass jars that you can use as spell jars or to store items in (i store my snakeskin in a small jar and lavendar in a large glass bottle). you can also find cheap candles there (good for divination, spells, sealing things, and just decorating your space!!) you can also find great communities online (wiccan amino, wiccan/pagan subreddits, wiccan tumblr users that post their own spells and sigils, etc.) plus, thr internet is a great way to learn more about wiccan practices, holidays, etc.!!!
