I bought from here -
http://www.88radio.com/
I'm in the UK, and was under the impression this company was situated in Hong Kong - but reading up further on this company, it would seem they also ship from America.
Their website contact info' says they're in China/HK.
My guess is that when checking out, the postage I was initially charged was based on them shipping from HK - but they then realised it was insufficient as stock was only held in the USA - who knows?
If I'd have paid the extra $40 demanded, my total shipping would've been around $85, and from the USA I would also get taxed for the import fees. Fees when importing from HK are reasonable, & shipping is normally cheap, too.
The costs were too excessive in total.
My gripe wasn't really the incorrect postage charged at checkout, it was more to do with contacting them & asking why my order hadn't been shipped in nearly a week - then to be told about incorrectly being charged for the shipping when it should've been done when noticed by 88radio in the first instance.
It seems like a poorly run company with not a lot of feedback anywhere, but my experience might just be a "one off" & mistakes do happen.
I definitely won't be bothering again, though.
