This is not from the official site and I doubt it's secure to buy from unofficial stores.
On the official site of coldcard, I don't find they're still sell the MK3 version since they're currently sell the MK4 version and it cost you $147 (they don't have a promotion for black friday [1]
On the official site of Bitbox, they're sold it for $125 [2] how can this site sell for $108? are they don't want to bankrupt lol.
Ledger also have an interesting promotion where they give you up to $30 worth of Bitcoin during black friday promotion [3]
