I just wanted to impart some knowledge about shopping online from Illamasqua to any UK buyers who are thinking of purchasing. It may help. I have a massive collection of Illamasqua and most has been done online via www.illamasqua.com/shop.
1. Although Illamasqua give 3-5 business days to get your item, I find that eight times out of ten my order will be shipped the same working day (or the next if out-of-office hours) via a 24hrs service. For example, one of my more recent orders was made at around 10:00 PM on a Monday. Being a bit of a night owl, I decided to make another order at about 2:00 AM Tuesday. At around 10:00 AM on Tuesday I received two e-mails saying that each package had been dispatched. They arrived Wednesday.
2. However, I have noticed that around times of peak chaos at Illamasqua it may take the 3-5 business days for you to get your items. But this is rare. The most recent one was the Thursday-Monday that sandwiched the opening of the flagship Beak St. store. Understandable. The orders were still received within the 3-5 business days.
3. All of my orders have been dispatched using DHL. They send you a message to say it has been dispatched but it is a bit of a work in progress like some aspects of the site. They give you a "tracking number" but it's not actually a tracking number that works on DHL... I guess they are still relatively 'new' but should patch this non-info up for customers in time.
4. Typically packaged in a black cardboard box, sometimes generic brown. Inside is a printed invoice slip of the order. Your item(s) will be wrapped in enough (but not a wasteful amount) black tissue paper and surrounded by nests of black 'stripped' paper. Makes your items look like precious eggs in a nest. Or maybe I read into things too much. Note: I use my black nests of paper to stuff my shoes with. They are ideal for this, great way to recycle them and it actually looks quite good.
Thought this may help if you are umming-and-ahing over where to purchase from online. Considering you almost always get 24hr DHL courier delivery and they package things well, £3.50 is definitely a good price.
PS. I've made one Illamasqua order from ASOS using Super Saver delivery and one using First Class delivery and both were a disaster. The first was the Kabuki brush and the box had clearly been used before, had one bit of sellotape round the edge (no glue), no protection for the brush on the inside save for a lone floating air-filled packet which wasn't even touching the brush and the brush's seal had been broken and it was out of it's translucent Illamasqua case. Asked for a replacement but they said they had no more, when you could buy it from the site the whole week after and it must still be there now. But I'd say Super Saver is a good way to go if you're not buying anything hygiene-related and don't mind when it arrives. It does still beat the 10% loyalty discount all-in, but I'd rather pay a bit more and have items packaged and dispatched the Illamasqua way.
I first got interested in it after seeing a YouTube clip of Courtney Love on the Jonathan Ross show. A bit of googling and I got to the Illamasqua blog. Alex Box had used Vow pencil on the lips with Brilliant (clear) lipgloss over the top.
