Incredible price for a FURminator large, long hair. I shopped for one last month and the cheapest I found was an ebay "backyard seller" offering it for $40 + $10 shipping.
Knockoffs are available on ebay for $10+ and may be ok but the quality does not look up to par.
Amazon Prime is required for free shipping.
Shopback and Cashrewards(currently) offer 6% back at Amazon AU.
This is listed as a new seller, and there is no indication for how long the price will last. I have one due for delivery tomorrow.
A comb is also a must for proper grooming of dogs with an undercoat. I bought one from ebay recently and this Amazon AU product is 40 cents cheaper.
7.48" x 1.57" - $5.39

I know i'm going to be Negged for saying this, but as a professional groomer.. DO NOT USE THESE.
It cuts the hair, and will make your dog actually grow back fluffier (Golden / Lab / Husky / / / etc) use a Rake / comb / slicker only for longer hair dogs, and rubber brush for short hair.
