News from the store:
My international shoppers may have noticed the lack of a First Class option lately. It was a glitch introduced by the USPS themselves, now found and matched on my end. (By my awesome tech support.)
Hm, you know this might be happening a lot of places. And might happen again if the USPS corrects that misplaced hyphen. You are welcome to tell me via comments/contact us page for a faster fix.
