Why are tyres in oz so expensive

[Louwai]

So if Bunnings low end profit is 100% I would hate to think what there top margin is its a Joke and what gets me is that we all support these rip off's. Its funny but I mostly go to my local hardware not Bunnings.

We're getting off topic (Tires) but these examples are the best I can give cause I don't deal in tires.
I can only assume something similar is happening.

It all comes down to who buys what & how many. If you are willing to buy from overseas, then do it. If you need someone in the US to do the dealing & re-sending for you, I can arrange that. But for tires, you'll need someone here to fit them.
Also, if you are not familiar with the "Personal Importation" rules of Australia, then I suggest you study up or ask. There are several hidden costs which newbie importers can sometimes miss & then they get a surprise at the end.

Getting back to my telescope scenario, I ONLY buy major components from overseas. Over the past 5yrs I've saved approx AU$5k by buying my bits overseas & having them shipped.
