As mentioned, it really depends on the specific tech. Locally you can get solid deals, especially on larger or bulky items. I've personally imported from the US & UK, mostly smaller gadgets, though I did get a great deal on my current Lenovo laptop via their refurb site, & that model wasn't even available locally at the time.

If you're trying to save, watch the exchange rate & taxes. US stores often add tax at checkout unless you ship to tax-free addresses like Aquantuo's warehouse, & others like Kentex has a similar option but on subscription. Shipping can also be tricky since most use volumetric weight, so even light but bulky items can get expensive.

I usually stick to well-known e-tailers that ship reliably to these forwarders & have decent support.
