My Audible Premium Plus special promo deal (4 mths @ $6.95/mth) expired yesterday. On going to the Audible US home page today, I was presented with an offer of one free month (trial) then $1.95 per month thereafter for Audible Plus. Regular price is $7.95/mth. Naturally I accepted the offer!
There seems to be no end date for the $1.95 pricing

so I will stay on it for as long as it lasts. I have MANY books added to my listening library and was in the middle of a juicy one ("Badlands" by Peter Bowen) when my membership ended yesterday. So I am one happy camper today. Didn't want Audible Premium as I struggle to select titles to buy with my credits. (How to choose???) This solves my dilemma with an extremely attractive price tag.
Just posting this in case others qualify for the offer. If your membership has expired, it's worth checking the home page. Or, sign out of your account and go to Plans & Pricing. For those who aren't aware, Audible Plus is a subscription for unlimited listening to a (very) restricted subset of Audible titles, podcasts and Originals.
