I'd be happy to drive you (up to 2 people) from Hurstville or a train station in the St George area and go to Costco.
Costco is a members only shopping experience and there are a few locations around Sydney but this is for a trip to the one at Crossroads.
I can get you in with me based on my membership. Payment usually is by the member only but I can take cash payment and often the checkout people will just let you pay for your stuff.
Bulk buy toilet paper, seafood, meat or pizzas as well as lots of other goodies.
Personally I like their sweets, nuts and Skippy Peanut Butter (Crunchy of course!)
I can drive you and take you along and either guide you around or just leave you to your own devices till you are ready to go.
The rate is for a one hour session but happy to have the rate cover up to 2 hours from pick up to drop off.
Whilst it may sound expensive, a taxi trip could be a lot more.
