We have had several delays in international shipping for both United States Postal Service First Class and Priority Mail shipping. Guarantees from all international shipping providers have been suspended due to Covid-19. Please understand if you are ordering internationally shipping times may vary drastically. It is our policy to offer a refund if the order doesn’t arrive in 12 weeks from ship date with international shipping per industry standards during this time.
There doesn’t seem to be a systematic reason for the delays. As an example have had First Class Packages arrive in the UK, Finland and Australia in 3-4 weeks while packages to Germany have taken 11 weeks.
If you need your order shipping quicker we can work with UPS but the costs will likely exceed the cost of the order. Please contact us for more information at:info@boringresearch.com
