Yep you are right. problem is most big suppliers and brands would not even know it's for sale so they will never even bid.
NOTE: for anyone stumbling into this thread later, this is an aftermarket domain not an expiring/dropping domain.
I think this seller is being smart as they are maximising their odds of selling to a big supplier or brand as:
1) They have a "for sale" banner on their site linking to the listing.
2) They have it listed in the standard catalogue so if it gets turned in it will revert back to a normal sale with a "make offer" and a "buy it now"
3) They may have noticed the recent interest in hair related sales getting good retail prices so they are testing the waters with a category killer like hair.com.au.
If the listing gets turned in, they have learned the depth of the current Netfleet buyers pockets and they can try again in 4-6 months (or if they notice a run on hair related sales in the future)
Eventually a "big fish" or their marketing team or SEO advisor or friend at a BBQ will notice the domain and will start the ball rolling towards a sale. As the saying goes it helps to have a line in the water and bait on the hook when fishing.
Judging by prices seen recently on car related domains (and I am including used.com.au) in that list, I'd say it is a good idea to test the waters for car/motoring related domains.
Insurance and Property related domains also seem to do well historically, most recently Granny-Flats selling for a good price.
We also seem to do well with travel and accommodation domains.
