Did you ever consider the fact they are probably buying them from just a US source in large bulk and having them shipped by cargo container to GB. You do know that the GB to US conversion is in your favor by basically 2 to 1.
And you also just contradicted yourself. Your trying to quote ebays prices to our wholesale suppliers. Ebay sells most items below wholesale. Not to mention you also need to look at the market that your trying to sell in.
Ive also done some research on several treadmills from retail locations in the us based on the brands I see selling in the UK.
Duratek fitness which happens to be a buisness seller ,sells thier own units on ebay.co.uk and they are the biggest treadmill seller on ebay.co.uk. They sell thier own product. And they sell the high majority of units sold in the UK.
There is another seller nextdayuk that sells unbranded treadmills. You cant even find specs on these machines on the internet so its a definate possibility that this company manufacturers thier own units.
All the other units I see that have sold are personal items or items being cleared out for way below thier original value.
Many of them are also brands that I cannot even find using a simple google search.
So you expect us to find you a source based on limited information on a field that you yourself have limited information on? When you research a product you need to research the sellers as well. Whos selling the most items. What thier name and thier affiliation to the product they are selling. If you cannot locate that brand on google then its possibly a house brand meaning the seller that is selling them is also the manufacturer.
Heres some advice. DO MORE RESEARCH... You have a very big advantage and you dont even know it. You have the ability to buy items from the USA for basically half of what we have to pay for it due to conversion rates and you can sell them on Link hidden: Login to view for more then we sell them in the USA. You have alot more potential then you think. But you need to do more research in the area you want to jump into. I would personally stay away from heavy items though if you plan to purchase from the USA unless you plan to ship by cargo container loads.
