Oral-B Pro Health Complete Defence System Whitening Toothpaste 110g

Is this one worth buying?

Oral-B Pro Health Complete Defence System Whitening Toothpaste 110g is currently listed at $2.75 at Woolworths, against a usual price of $5.50. The dollar saving is small, so treat it as something to add to a shop you were doing anyway rather than a deal to chase.

Razor blades and electric toothbrush heads are the standouts. Both are expensive per unit and both keep indefinitely, so buying a year of blades at half price is one of the few grocery decisions that reliably saves real money. Bulky, cheap items like a single bar of soap are less worth the trip. Check the unit price on multi-packs — a half price 4-pack is not always cheaper per item than a full price 12-pack.

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.
