"PM sent" - what's the point?

[Duane Hess]

Maximilian:

You should be welcome to inquire. The person posting a "PM sent" does not speak for the seller. A "PM sent", in my opinion only "stakes a claim" from the perspective of the person who posted it. Often sellers have multiple items, whether they list them or not, so a "PM sent" may be in regards to specific items.

I have sent PMs to sellers who list a single item asking whether they might have an associated item although the item listed is not of interest to me.

I have posted "PM sent" myself. Mainly due to the realization others (including myself) often do not check PM or my regular e-mail on a daily basis.
