I bought these a bit over a year ago from Amazon paid like $16.80 but it was a USA import.
The Channellock GL10s are made in MERICA, they have good quality harden teeth offering good grip heaps better than the cheap multi-grips. They also stay in place better because of the groove system when choosing a size and don't slide around as much as cheap multi-grips making them easier to use one handed.
Same price at Amazon currently $16.13 which is lowest price ever according to Camel. At Bunnings the normal price is $37.95.
