Finish Ultimate Plus Dishwashing Tablets Lemon 14 pack

Is this one worth buying?

Finish Ultimate Plus Dishwashing Tablets Lemon 14 pack is currently listed at $10.00 at Woolworths, against a usual price of $20.00. That is a large enough single saving to be worth a deliberate trip if you already use this product.

The trap in this category is pack size. A half price 30-tablet dishwasher pack can still work out dearer per wash than a full price 60-pack, because the larger pack carries a permanently lower unit rate. Australian supermarkets are required to show a unit price on the shelf label — use it. Concentrated laundry liquids are the other thing to watch, since two bottles of the same volume can be rated for very different numbers of washes.

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.
