Did I do the yellow letters order wrong? Help!

[Aroldo Villarreal]

Hi, it's my first time that I ordered from yellowletters.com and I hope I didn't do something wrong. I just opened my mailbox and found all of the postcards in there. I thought they were going directly to the persons whom I was marketing to. Is that supposed to happen? Or did I do something wrong? I'm assuming I can go to the USPS and drop them in the bin, but don't know if they'll mail since they already got mailed once, to me. I hope it was not a mistake!
