Poirot -- sorry, but in what sense did a referral link work for you? I tried G3's link, which an earlier poster said worked and here's what I saw:
* It opened up a window to Republic's "what phone do you want?" page.
* I choose two phones and then clicked on "Plans and Checkout." The costs for the phones were listed, with no indication of any discount.
* I chose a plan for each phone. The updated costs were listed, again with no indication of any discout.
* I said no to accessories and finally got to checkout, still no indication of a discount.
* I entered all the info they asked for, including credit card -- still no indication of a discount.
* I stopped at the "Verify" step as I believe that clicking "Verify" would charge my card, again with no indication of a discount.
Everything that shows up after clicking someone's referral link is exactly the same as I got when just going straight to the Republic site with no referral link. I see no indication that I'll be getting any sort of benefit from that link, so I didn't complete the transaction.
