No hardware wallets are discounted. I doubt you will see that with the current chip shortage, COVID-related disruptions, inflation, etc. Trezor as a whole company is not celebrating an anniversary. Only their Model T hardware wallet is 4 years old. That's why the special offers don't include any accessories for the old Model One.
I did not look deeper into that, that is true, only Trezor T accessories or something is what they have discount for, but it would have been better if Trezor T was included, this could have triggered some people to never lose the opportunity, the people that might later go for another hardware wallet.
Is this Trezor making early first April jokes with
50% discount on accessories or what?
Nobody cares about stupid accessories like covers and screen protectors, so they should give real discount for their overpriced model T devices.
I have two Android phones. Could you believe I did not use any case and screen protector, I got both in February 2020, and nothing ever happened to both. Which means the accessories are not what I can go for.
What I just know is that more people would have bought even the accessories more if Trezor T has discount too, even if it is just 10% to 20% discount in a way the company will not lose. But this is just my say, Trezor have their own opinion to make.
