you either like Chinese imports or you don't.
China has the advantage in that postal costs are cheap, bearing in mind postal costs are also subject to vat.
all the big vendors like Ebay, Aliexpress, Banggood, Hobbyking etc will apply and collect vat from you on your purchase, including postage.
An example, I recently purchased some electronic items on Aliexpress for an amount that would not even pay for postage in the UK let alone the items themselves.
Another anomoly in Chinese trading is the problem of returning faulty goods.
To post a small item costing £5 would cost between £10 and £20 depending on whether it is tracked etc so not worth returning – the Chinese suppliers know this so you have to be on the alert with who you are dealing with.
Personally, I only order expensive goods if the item is supplied from a warehouse in the UK or EU, Banggood springs to mind. Anything else I am prepared to accept the 'possible' loss as down to experience.
To date I have not been let down by any Chinese supplier and continue to benefit from low prices and cheap postage,
Choose right and the item(s) will arrive quite quickly, If I am desperate for an item I will pay the premium if necessary to get it from the UK.
Do not be fooled by some ebay vendors who advertise as being in the UK so delivery will be quick, some just pass on the order to China and give you a raft of excuses when the item is not delivered during the timeframe they have given you. I have been stung a couple of times with this – caveat emptor
