Some not-so-fun news, unfortunately: the USPS is raising their shipping prices as of January 17th. Boo. :(
This price increase is fairly dramatic, especially for international shipping (going up an average of 21%, yikes!). Other than a 200+ page PDF detailing the pricing changes for each mail service and weight group, the USPS hasn't released the new pricing on the website yet. It took a good bit of digging to find what the prices should be, but the website shipping prices should be accurate (please keep in mind that these new prices also account for package insurance).
Because my lead time is currently 5-8 days before shipment, I have raised my shipping prices before January 17th so that they will accurately reflect the new pricing once an order is shipped.
I completely empathize, and want to apologize for any inconvenience this causes, especially for international customer, but it is what it is, I suppose.
Thank you to all of my customers for your understanding and support!
