7/19/2021 Update: US Mail is still running behind in some cases, (especially Maryland) but transit times are much improved from the previous few months. If you need your diagram(s) quickly, please select UPS at checkout. For Maryland we highly recommend UPS if you want your diagram in less then a month. We have negotiated a flat rate of $9.95 per shipment. (Residential & Extended Area surcharges are included) East of the Mississippi should receive items in 2-4 business days or less, rest of continental US in 4-6 business days at most. (See Map here) The Estimated Dates you see on the USPS site are not guaranteed. UPS dates on the other hand are pretty accurate. EU countries please note that the VAT laws have changed effective 7/1/21. Your carrier/customs will now be looking to collect VAT upon delivery
