Vendors have 4 days to put your order in transit. If they haven't put shipped it in that timeframe and changed the status to "in transit" then you'd be able to cancel your order after those 4 days pass. Since they did mark it in transit (and hopefully did actually ship it), you'll need to wait and see if you receive anything. If you don't, you can click on "resolve" and take it to the resolution center in hopes of getting some amount refunded. In the meantime, stay in escrow and you should be fine!
