Read their reviews where they can't curate them, Trustpilot, not their own widget; read the one-star reviews and watch how they respond when freight goes sideways. You can see our Trustpilot reviews here
Ask what happens when a unit arrives damaged, you're listening for a person who owns it, not store-blames-manufacturer ping-pong.
Get the delivered price in writing before payment, "freight quoted after purchase" is the oldest move in the category.
Ask for a name, if nobody owns your order, nobody owns your problem.
