Buyer order and pay for a tire pressure gauge on a SUNDAY that was listed with free First Class USPS shipping. Then ask me to ship same day (he said because my listing state that, except that I it's also stated that I ship same day from Monday through Friday ONLY), and said he expect to receive the item the SAME day on the SAME Sunday he ordered it!! Even Amazon don't offer this crazy fast same day shipping service on a Sunday for free (yet at least).

When I told him that his item will be only shipped on Monday morning, and that because he selected the free First Class USPS shipping at checkout, his item will take approx. between 3 to 7 days to arrive. At this point, the buyer asked me to cancel the transaction, which isn't really easy to do since the shipping label have been already printed and paid for. Now I will have to call eBay and see if there is a way to cancel this transaction, AND get also a refund on the paid label as well.

Buyer blocked, and I recommend you to do the same to avoid the same troubles.
