Checking Apple's store, I can't find a cheaper configuration than $5100 for the M5 + 128GiB version.
Here in Europe, including 21% VAT, that's €6.124,00 ($7.094,35 equivalent).
Because of pricing strategies and such, the 128GiB version comes with a 2TiB SSD at minimum, and also requires the M5 Max (not Pro) at its highest configuration.
Not sure if this is new, but it should be noted that these laptops don't come with a charger any more.
70W USB-C Power Adapter (included with M5 Pro with 16-core GPU)
96W USB-C Power Adapter (included with M5 Pro with 20-core GPU, configurable with M5 Pro with 16-core GPU)
USB-C to MagSafe 3 Cable (2 m)
Devices should be offered without a charger. There's no law that states that that should be the default configuration. Nor that the charger should cost extra.
