Our current date is 8/14/21 which is just over 6 months out. About 50% of the guest list is from out of town, primarily out of the country from Canada. If COVID isn't much better by then, and the northern border is still closed, we are planning to postpone to make sure the people important to us can attend safely. However, there are items that we want; decorations, signs etc. that will be dated with the wedding date. Knowing that there's a chance of us postponing the wedding. How late can we order these items to ensure they arrive before the wedding date?
