I took a chance and ordered frames without lenses to Canada. They were delivered in about 2-3 weeks without any surprise inflated brokerage fees. UPS often adds $50+ in brokerage fees. From the tracking number, it looked like they were being delivered by UPS but arrived with USPS stickers and delivered I think by Canada Post. The frames themselves were a little twisted but my optician was able to straighten them.
Seeking tracking number, was sent right away.
