Visit any local Yankee Candle store in person. The best discounts are ones you can buy on the spot because you don't have to pay shipping costs! Yankee Candles can be quite heavy! Discounted candles are often grouped together in a special section of the store and discounted anywhere between 5 to 50% off.
Search the Yankee Candle website for discontinued candles (look for the 'What's On Sale' link). When the local stores run out of a discontinued candle or fragrance, the company website may still offer it online until supplies run out.
Check online candle shops or local candle stores and specialty shops like Cracker Barrel or Bed, Bath and Beyond for discount Yankee Candles.
Search online marketplaces like Ebay, Amazon, Craigslist, Bizrate, and Shopzilla for discount Yankee Candles. You can buy them new or used - with the used ones often never opened.
