I'm sure many people already know this but figured I'd write about my recent experience in case in enlightens a few people.
To tell the short version, I ordered a product on the 19th of April that was listed as "Low Stock" and told on my order page that it would be dispatched on the 26th of April.
Come the 26th of April, the ETA was removed with no ETA instead saying "We're running slightly behind but you can expect to hear from us soon!".
I contacted the seller yesterday (2 days after it was originally meant to be dispatched) and they said that "After checking, I can see we have 3 stocks of this item on the way to our warehouse, it will take 3-4 working days."
So while the listing said "Low Stock" it should instead have said something like "Pre-order" or "Back-order" which is ultimately what it turned out to be.
Moral of the story, for the seller I interacted with at the very least, they weren't able to show correct stock levels and I ended up back ordering a product that I was told was in stock. So if you're impatient like me and want your items fast, I wouldn't trust the Kogan 3rd party stores' product pages.
Happy to read the long version too if you have it
