I am a fan of their down jackets and other items. I always use the "collect at convenience" store option as I have a horrible neighbour and despite me asking couriers not to leave things with him, they do, and I never get them.
The last THREE orders I have placed have been lost. When I track with HERMES, I see "missing pre-advice" and this means the item is now lost and will be returned to Uniqlo. After the first 2 orders Uniqlo advised me this was an IT error and was now fixed. I placed another order. Same thing has happened again.
This particular order was a gift for my God Daughter's birthday which she specifically asked for.
After the first 2 lost orders I did get a response from them giving me codes for 10% off and free postage but to be honest I don't think I will be using them again.
