Pressed discs are much more archivally (not sure if this is a word)
sound. Burned discs only have about a 5-8 year lifespan pressed discs
can last much longer to the 15-20+ year marks.
I do not know of a shop, but usually when you do pressed discs you
cant do a few its usually like getting a 100+ disc batch, but that
information is likely outdated.
the main difference between burned and pressed discs is that pressed
discs actually don't have much of a dyde but more of an etching
process burned/RW discs have a dye that reacts to air and light. and
interestingly the lexan that's commonly used is gas permeable.
I know this as right now the museum i am working for is running into
large scale archival solutions for video/audio that does not have a
lossy result. (if someone wants to chat about this feel free to
contact me as we don't have a true answer yet)

A mouse trap, placed on top of your alarm clock, will prevent you from
rolling over and going back to sleep after you hit the snooze button.
