Is this properly accounting for the regional pricing differences of "good girls" and "bitches"? Lil Wayne has lived in a sprawling mansion in Miami, but also now lives in New Orleans. Are we just supposed to accept at face value that the costs are fixed across both localities?
Additionally, Kanye appears to be referencing wholesale costs of "bitches" as he's talking about getting them in quantities of 1000, while Lil Wayne is clearly buying in retail prices at only 12 "bitches" at a time.
There's too many inconsistencies to determine objective pricing from the data provided.
