As for everything being on sale, I have 66 games in my backlog plenty of which either haven't been on sale or at least haven't for some time. A few highlights:
Patapon Remastered (Never once seen on sale, added 12/23/17)
ChaosChild (Seen on sale once, for a lot, added 12/23/17)
Vector Unit Triple Pack (was on sale a lot for awhile but hasn't bene for a long time, added 1/3/18)
Indigo Prophecy (Never seen on sale, added 1/6/18)
Nitroplus Blasterz (Was on sale once around the time I added it to my list, only one sale since and nowhere near the historical low, added 1/30/18)
The Rabbit Hole (Don't remember ever seeing on sale, added 2/18/18)
Dexed (was on sale awhile ago but hasn't been for some time, added 2/20/18)
Tons of PSP/PS One Classics which never go on sale including Wild Arms 1/2/XF, Hexyz Force, Growlanswer Wayfarer of Time, Jeanne d'Arc, Summon Night 5, Tomba 2, Vib-Ribbon, Gradius Collection, Gungnir, Persona 2 Innocent Sin, Knights in the Nightmare, Ys Seven, Ygddra Union, Arc the Lad II. A lot of these are first party which makes it even worse.
VA-11 Hall-A (Never seen on sale, added 7/3/18)
Then there's admittedly plenty of stuff which has gone on sale but not for a price I'm happy with yet.
