Hi Vicky,
There are sales on at most times of they year. ie. they have just had a big 4th July sale. The next one will be 'back to school', when Jeb Bush lets them have a tax free week on school stuff and clothing (under $50). We are gutted, as this has always been in the last week of July, but this year has moved to first week in August!
But, with all the outlets, there are plenty of bargains to be had.
We personally prefer the premium outlets near LBV, and you can join the VIP club to get extra discounts there. Last year my DH and DS got some lovely leather Timberland shoes for less than £20.
Happy Shopping!
Tracy
