Mike,
Considering where you are coming from, you will probably find some good deals. Florida's state 6.5% looks much better than our 13%HST, and as long as our dollar remains near parity, prices for many things look pretty good - kind of like Costco but you don't need to buy by the gross.
We did Premium Outlets last March and found lots of bargains for me. DW didn't do quite as good, but still found a few good things. The main thing is to hit both Prime and Premium Outlet web sites first and see what stores are there and match to your desires.
I loaded up mostly on Columbia clothing at (IMO) Mark's Work Wearhouse prices.
Make sure that you also look for additional discounts available. We took the Orlando Magicard (online printable from the Orlando Convention Bureau) to the Customer Service booth to get a book full of additional discounts. At many stores, that'll knock another 10% off the price.
Happy Shopping!
M Ross
