I need help finding envelopes in our area. I would like to go to the store and pick them up if possible I know I can find them online but I would perfer to pick up if possible. I am having an awful time finding square envelopes 6.5"X6.5" or larger if anyone knows where I can find them in the Mechanicsburg or Harrisburg area. I am willing to go just about anywhere. Thanks for your help!
