I scoped out a nearby closing store today and confirmed they're doing the 5 for $5 but there was sadly not much left of interest.
I ended up grabbing Soul Calibur V for XBOX 360 (CIB), Touch Detective 2 & 1/2 for DS (cart only), & Picross 3D for DS (cart only) for myself and TMNT for 3DS & Just Dance Disney Party for XBOX 360, which I traded in to another store for $6.60 cash.
So basically I ended up with 3 games and $1.10 more than I started with, haha.
Also, with Elite Pro officially ending in 2 days, I went ahead and cashed in my banked PUR points (had enough for a $30 Switch game) and dumped the rest of my decently-valued trades today.
I'd already traded in $492 worth of stuff for cash this month and I just got another $297 today so I'm fairly certain I'll be hit with a trade ban but with the 20% bonus going away I'm pretty much done trading stuff in anyway.
