Hey there Chelsie! 
It’s so great that you’re wanting to support your friends and coven members here on Spells8 
I just want to point you in this direction → Coven Member Shops 
← We actually have a whole thread of current shops owned by members here!
If you’re a small business owner and want your shop added to that list, let me know!
I don’t personally sell crystals but I do have my own shop of crocheted goodies
