I reckon that I have probably saved my membership cost in fuel over the last six months or so. Consistently up to 10 cents a litre cheaper than other places.
Tyres are also considerably cheaper if you run Bridgestone or Michelin. I saved $40 a tyre on the RTV ute the last time I got tyres.
I like the items that are not easily available elsewhere such as the Whalen storage shelf
Whalen 4 Tier 77" (195cm) Industrial Storage Rack | Costco UK -
I'm less convinced that they are a competitor for the main supermarket chains though, we don't buy many groceries there.
