Yes, all that's true. But just to clarify, FrameUSA's frames typically come with glass and I think there may be type of glass options too. I think you could probably find a nice looking frame - with glass - at a reasonable price there. Best wishes.
edit: Here's an example:
10" x 20" Black Picture Frame in Wid
View attachment 47281
$45.67 (Note: I think a 10x20 may be a little more expensive because it's not a typical size; there may be other less expensive frames as well. This was one I found with a quick perusal of the offerings)
Frame will come with a standard pure white (
B403) mat.

Frames will come with
cardboard, a screw in sawtooth hanger for wall framing, and
styrene. (If it's an issue think you can request other options, or omit the sawtooth hanger, as galleries/exhibits often do not accept them. However, plein air events may accept them.)
