Yes, you're correct.
NO Tower Records in Florida.
I would say Borders has a decent selection of jazz. Last time I was at the Virgin store, I wasn't too impressed. (haven't been back)
Course, every so often, Virgin does have good CLEARANCE items. I think they had a big clearance sale at the end of the last year. Others on the board raved about some good deals the first day of the sale.
I use to go to BLUE NOTE, their selection was pretty good. But since they moved the jazz section to a warehouse-like building, I haven't gone back.
