I only recommend to order from official website. From http://promo-wallet.com/ you can see actual prices, discounts, promo codes, but you will not order from that website. If visitor want to order, will go to official website, Trezor or Ledger shop.
It redirects us to someone's referral link at ledger or trezor whichever we click, and I'm damn sure it's yours. Nice trick on getting everyone to buy and get ya some commission while motivating others to go for hardware wallets. Nice smart use of your brain that you didn't give your referral link here and followed the rules, and gave it through your website while helping others by providing them with coupons and better information of all sort of hardware products mentioned there.
