Are there any good deals in general that are worth snapping up because of its prices compared to NZ prices?
I've seen some deals on things like hand soap (thanks Wakrak) being posted here so just wanting to know what stuff can be stocked up to save money.
Looking forward to everyone's responses!
Depends what you're after. I've bough household items like the soap you mentioned, socks, helmet, bike lock, razor blades, toothbrushes, monitor, phone screen protection, sewing gear (pins, scissors, pens), desk lamp, condoms, microfiber towels, salt & pepper grinders, Nivea products … and the list goes on.
