I got an email shortly after submitting the order with the subject "Your kmart.com order is processing" which has a receipt in it. It lists the expected arrival date as 5/19 for some reason but other than that everything is correct.
That's worrisome I got nothing. Even checked all my spam and trash folders. Wondering if I should ask them to make sure my order is valid or just wait and see.... Think I'll just wait and see; if the order doesn't go through, that's fine by me.
Thanks everyone for your feedback!
