You can sign up for USPS Informed Delivery. A free service. You will get a daily email with an image of each letter you will receive in the mail that day. I have found it to be 95%+ accurate.
Lawnboi - This post and picture are primarily for you. My T1, T2 and T3. I took the picture to document the foliage color inconsistency that occurred over time. Thanks again for letting my dad and I try on your T1 before we made the leap and bought our T1s.
I've used an Aeron by Herman Miller for 7 years. Still in excellent shape, full working condition, very comfortable. I bought it as an open box item from https://www.madisonseating.com/ at a good discount. I would do this again.
