I went there on Black Friday, by mistake, i completely forgot and it was very, very busy!!
However, I live nearish and go there about 3/4 times a year. It’s currently better for bargains than it’s been for a long time. This summer there were sweatshirts in Gucci discounted that were in the main boutiques full price.
Basically, not much sold for designer shops last winter, so there is lots to sell on.
If you are prepared to be open, you might just be lucky.
My tips, avoid the ‘made for the outlet’ stuff. It’s usually obvious, but be aware it exists.
Google anything and check you’ve got the best price- some times the OUTNET is cheaper.
Don’t expect it to be a fun shopping trip, usually it’s only for the very determined. There is a virtual queue for some stores, which can be a pain and mean you miss out some places.
If you can’t find your size, ask, there’s usually stock not out. Especially in the higher end stores.
Finally, don’t expect it to be very cheap. 50% off a lot is still a lot! Designer prices have gone crazy in the last 5 years - all bargains are relative!
Aim to go early or late, and I would recommend late. The middle of the day is very busy.
I often go and spend nothing, and then I’ll occasionally find lots to buy. It’s just luck.
