Does anyone have a clue how on earth can the Chinese sell at such price tag? …
as reksbg says
You have a few things to think about, one the fakes these are down right fake /out of spec devices, radio shack used to sell packs of devices transistors remarked.
two new old stock, a plant has finished a order, and unused parts are no longer under control standards/ can't trace how they have been handled.
Then you have the reclaimed parts, scrap boards striped of components, I think I have bought some of these in the past.
Also they use china post, almost free to use, but they charge you $10 postage.
Look at what people say who have bought from them, I have a few sellers that don't charge till I have the items.
If they offer free post and small orders, buy a few days apart then you have a chance the item slips through customs & taxes are not charged at full rate, or not all.
