This is not the typical "hook-up" as one would find on the street corner. This is special pricing, similar to "resale" pricing, but not exactly the same.
This "hook-up" can be described as the pricing one would get while shopping at an outdoor swap meet or from a street vendor.
This does not mean that one is selling "hoe's" (that being of the gardening tool or the woman prostitute)
"I can get that at hoesale" This would mean you are not really getting a deal at all and may be even paying more than retail. The item maybe used, damaged or even carrying some type of disease.
Seller: "I have some cheap Gucci bags at hoesale"
Customer: "Those are not Gucci bags, those are Chucci bags!"
