I tried finding out the answer to this question by performing a search but I couldn't find anything relevant.
Do you find that you have more success with your spells when you use better quality oils/candles/herbs/foods etc? For example, buying a certain oil at a specialty shop rather than dollar store or does it not really make a difference? I know a spell can be as simple as using just your mind and no fancy equipment but I was wondering if the results are enhance when you do use more good quality items.
