Ambi Pur are offering a 50% off voucher for the Ambi Pur Set & Refresh product range at Woolworths.
Woolworths Online shows the normal price as $6.44 for the diffuser and $5.15 for the refill. It comes in two fragrances. The online store highlights the diffuser as an "Extra Special, Extra Simple" Everyday Rewards member price of $2.99.
I hope they have a better range of scents than what is listed on their online store.
