No you're good.

The page goes to an overall page that seems to show all the choices you've made thus far. The autofilled areas don't say what they are going to be, which makes you more sure this isn't real but a fun experiment. You proceed to a payment page, and surprisingly cheap for something that should be impossible to build or create in any way. You still don't trust it so you put in an expired credit card, which it seems to take without issue, "Weird" you said dumbfounded.

The page redirects to an expected delivery date, which doesn't seem to out of the ordinary if they are actually sending you the product.
