All three current Awazon Market mirror addresses, with a copy button on each. They are the same storefront three times over. There is no "main" mirror and no "backup": the market runs them as equals, and which one answers on a given circuit depends on your route through the network.
Copy one
Tap copy, then paste it into Tor Browser. You do not need to add http://; Tor Browser reads the .onion and handles the rest.
Check it loaded the right one
The address bar is your only receipt. When the page loads, look at the very end of the onion in the bar and match the last six characters against what you copied. If they do not line up, do not log in and do not fund a wallet yet. Reload, or try the next mirror.
Confirm the list against the signature on the verify page, or see when each address first appeared on the address history page.
