Monthly ritual supply budget

How much is your monthly ritual supply budget? I seem to always run outta supplies, which has forced me to really cut back on rituals which has me really doing nothing at this point. I always buy at the least costing. but right now, just candles and incense run me about $12 per month.
What do you spend, what do you do to keep things at a low cost, where do you shop etc. really would appreciate help.

Immediately I was reminded of this thread where people discussed how they keep themselves supplied without breaking the bank. It might help.
