Great prices on these OK PRO-branded, rubber coated dumbbells. Many stores will sell their equivalents individually for prices not far off what these are being offered for as pairs. There are also quite a few sizes in stock, which is a bit of a rarity right now thanks to the Covid-induced shipping delays.
These are the sizes they have in stock:
8KG - $60
10KG - $68
12.5KG - $84
15KG - $100
17.5KG - $116
22.5KG - $148
25KG - $164
30KG - $196
Shipping prices will obviously vary, and you'll have to run through checkout before it gets calculated. They ship out of Auckland, and free pickup (located near the airport) is available.
Barbells, kettlebells, benches and other pieces of equipment are also discounted.
Kmart and the Warehouse have similar in some sizes and with free shipping/ pickup may be worth a look.
