I've been searching these forums quite a bit, and found several posts about First Class Mail Parcel, but honestly found the questions a little rambling and confusing (no offense!). So I just wanted to say it plainly:
First Class Mail Parcel shipping option does not appear for our products in checkout.
- We ship out small model trains, they are light enough for first-class parcel rates.
- We did try enabling "First Class Mail Letter" as an experiment, and this letter rate did appear in the shopping cart.
Does anyone have some insight into this issue?
Thank you so much for your help!
