Plain White Unity Candles

Where can I get a plain white unity candle? I don't want to pay like 20 bux for just a plain candle...any suggestion on where I can get a plain on eto DIY??

THANKS!

I bought my online (since I bought 24 pillar candles for my reception and used one of those), but you can just go to Walmart, Target, Michaels, Joanns for about 2- 4 dollars.
