By Air Wick Vanilla & Himalayan Magnolia Automatic Spray Starter Kit

Is this one worth buying?

By Air Wick Vanilla & Himalayan Magnolia Automatic Spray Starter Kit is currently listed at $14.00 at Coles, against a usual price of $28.00. That is a large enough single saving to be worth a deliberate trip if you already use this product.

Tinned tomatoes, chickpeas, beans, coconut milk, stock and pasta all have shelf lives measured in years, so there is no real downside to buying ahead. Olive oil is the exception worth naming: it degrades with light and heat and is best used within a year of opening, so buying six bottles because they are cheap is a false economy unless you cook a lot.

Half price specials at both Coles and Woolworths normally run for one week, from Wednesday to the following Tuesday, and the same lines tend to come back on promotion every couple of months. If you miss this one it will very likely return — but the price shown here is the current one, and prices can change without notice.
