My order of filaments this Tuesday was delivered by OnTrac instead of UPS as before.
When I got the email from BL about my order was on the way, I didn’t notice this change and clicked at the tracking number which led to the login page for BL. So I thought that meant UPS didn’t have the package yet. Then yesterday (Thursday) the filaments arrived. That’s when I paid attention and saw OnTrac in front of the tracking number on the BL email.
So for small packages delivered by OnTrac, one needs to log into BL to see the tracking info.
