I need to access Amazon US, UK and CA to check prices and get links for affiliate links. I have found that sometimes Amazon will say that a particular product is not available, but if I change the 'deliver to' location in the top left corner by simply adding a US postcode (or, UK or CA as the case may be), then magically the product is available and shows the current price.

That has worked fine up until today. Now when I try to change my location, they want me to log in and register a full address. I could very easily just make up an address, but I don't want to do that.

I'm thinking that I might try a vpn. I won't be downloading anything, and I won't be streaming video or doing anything illegal. All I want to do is make it look like I am in the US (or UK, or CA) while checking what I need to check.

Not being familiar with vpns I searched ceo and found that Hola gets a few mentions. Ideally I'd like a free service. I see that Hola has a Firefox plugin (extension).

Anyone familiar with the Hola firefox plugin, or Hola in general? Will it do what I want to achieve?

TIA.

I've been using Free hola for years>>>
very pleased
use it with firefox and chrome

Yes

Windscribe is pretty good for a free service

Off to a good start here.

1. Hola
2. TunnelBear
3. Windscribe

I've installed Hola for Firefox, and it is brilliant (so far).
I currently have 3 tabs open. One each with Azn US, UK, and CA, each connected with their own IP.
