Elon Musk said Sunday night that Tesla received 200,000 "orders" for its Cybertruck, following an embarrassing debut.

@elonmusk: 200k

Hours earlier, Musk tweeted that Tesla had received 187,000 "orders." A prospective Cybertruck owner must pay Tesla a refundable, $100 "preorder fee." In his boastful tweet on Saturday, Musk conflated orders with preorders, which are distinct from a final commitments to purchase the Cybertruck.

On Saturday, the CEO wrote: "146k Cybertruck orders so far, with 42% choosing dual, 41% tri & 17% single motor."

According to the Cybertruck Motor Vehicle Pre-Order Agreement on Tesla's website on Saturday, this fee is fully refundable. But to actually purchase the Bladerunner-inspired Tesla Cybertruck, customers also have to take other steps:

"After you submit your completed pre-order and the options you selected become available in production, we will invite you to complete the configuration of your Vehicle. We will then issue you the Vehicle Configuration and Final Price Sheet based on the base price of the model and any options included or that you select."

It's less costly to preorder a Cybertruck than it has been to order previous electric vehicles unveiled by Tesla.

For example, to preorder one of Tesla's forthcoming crossover SUVs, the Model Y, customers had to lay down a heftier $2,500 deposit. In 2016, Tesla took preorders for the Model 3 at $1,000 a pop.
