It's not just bots, the supply itself was extremely low. Many redditors pointed out, using employees as source, some microcenters had a grand total of 10 gpus each.

This was nothing more than a paper launch.

Reading reddit forums this morning, it seems individual consumers didn't even get a chance to order - sites like Bestbuy went from "Notify when in stock" to "Out of stock" at 6am PST (supposed preorder open date).

Have a read at this. On this OP's opinion, which he's spoken to people close to the issue, Nvidia is purposely limiting stock and giving better cards to reviewers, in hopes they will be seen in a positive light, only to upcharge customers for lesser-quality models when the "stock" frees up in October.

I don't know if it's reliable source (regarding nVidia), but you'll be surprised to know that most manufacturers do this. That's why it's better to wait for those that post updates about the product after a certain period of time and to give a chance to the smaller reviewer that most likely had to buy the stuff to test it, just like everyone else.
