Gillette Venus bulk cartridges on Amazon Australia: the same "pink tax" maths, done properly

Gillette Venus Smooth cartridges fit the same "supermarket markup" pattern as the men's Mach3, but the gap is wider, and it isn't the same gap at every supermarket. A Venus Smooth 4-pack costs $12.60 at Coles ($3.15 per cartridge) and $18.00 at Woolworths ($4.50 per cartridge): same product, same barcode, a 43% difference between the two chains alone. The identical cartridge in an 8-count refill pack on Amazon works out to $1.42 each before any subscription discount.

That's a 55% saving against Coles' price and a 68% saving against Woolworths': on the exact same Venus Smooth blade, no brand switch, no compromise on the razor itself.

The headline comparison

The maths scaled to a real shaving year

Cartridge life for leg/body shaving is usually longer than face shaving: less coarse hair, more surface area covered per stroke before the blade dulls. The table below uses "replace every 3-5 shaves" depending on frequency, which is roughly what most reviews and razor manufacturers suggest for legs and underarms:

*Supermarket cost uses the Coles/Woolworths blended average of $3.83/cartridge. Cartridges-per-year assumes a fresh cartridge every 5 shaves (light), 4 shaves (typical), or 3 shaves (frequent).

Same shape as the men's numbers, bigger dollar figures: Venus cartridges cost more than Mach3 cartridges at every retailer, so the same percentage saving is worth more in absolute terms for a typical shaver.

The Subscribe & Save mechanics

Like men's razors, women's cartridges sit in Amazon's standard 5% Subscribe & Save tier, not the 10% household tier or the 15% baby tier.

• Gillette Venus Smooth 8-count list price: $11.39 (~$1.42/cartridge)
• With 5% S&S applied: ~$10.82 (~$1.35/cartridge)
• Coles 4-pack: $12.60 (~$3.15/cartridge)
• Woolworths 4-pack: $18.00 (~$4.50/cartridge)

The bulk pack size is doing almost all of the work here: even the list price without any subscription discount already beats both supermarkets by a wide margin. The 5% S&S knocks off a further ~7¢ per cartridge and sets up automatic reordering, which matters more for a product you don't want to run out of mid-shave.

What about cheaper alternatives?

The bottom line

1. The Gillette Venus Smooth 8-count refills on Amazon↗ cost ~$1.42/cartridge before S&S: 55% cheaper than Coles and 68% cheaper than Woolworths for the identical blade.
2. Coles and Woolworths charge meaningfully different prices for the same 4-pack ($12.60 vs $18.00), worth checking both before assuming "the supermarket price" is one number.
3. For a typical 3×/week shaver, that's roughly $94/year back in your pocket. For a daily shaver, over $200.
4. The S&S discount is only 5% here: the bulk-pack size, not the subscription, is what drives almost all of the saving.

The men's version of this same comparison (Gillette Mach3, same bulk logic, smaller absolute numbers) is in the Mach3 bulk cartridge breakdown. For the broader picture on which household categories pay off on Amazon Subscribe & Save and which don't, see the Subscribe & Save pillar guide.
