Diffuser refills

[Icelollycraving]

I use white company diffusers in white mint. Lovely but don't seem to last more than 7-8 weeks & I can't keep spending that. It seems ludicrous to not sell refills as the ceramic must be a considerable part of the price.
Anyway,has anyone found refill fragrances? I don't like synthetic smells like plug ins or Yankee candles.

You can buy them at John Lewis- Neom, True Grace and also L'occitane do them. House of Fraser also sells refill bottles with their own scents quite cheaply.

Thank you. Loccitane ones are reasonable & I like the look of the lavender & the verbena as I've had those fragrances before. Neom & true grace look nice but not terribly far off price wise,white company always have a 20%.
