I love reed diffusers. I buy my bottles at Specialty Bottle. The 4 and 8 oz. I buy a decorative silver cap that the reeds go through in the bottle at Advance Creations USA. My reeds I buy at WSP and the diffuser base at Peak's. I don't order thses alone if I order from any of those sites for my candles I just stock up on reed diffuser supplies to save on shipping even if I'm not running low. I sell my 4 oz for $9.95 and my 8 oz for $12.95. It costs me 2.12 for the 4 oz and 3.19 for the 8 oz. Again the silver cap is optional so it could be even cheaper. :smiley2:
