First, don't believe the hype about their beauty profile or glam bag customization. It just doesn't work that way. My family at one point had three separate ipsy subscriptions and to date not one has in any way consistently reflected the questions answered on the beauty profile. I expressed interest in a decent range of products, but specifically excluded a few things (eyeliner, for instance... or foundation, because I have a hard-to-match complexion) and yet it's guaranteed in every single bag at least 3 (usually 4) out of 5 items will be something I specifically excluded. I almost NEVER receive items I checked, even when I write to customer support to request them. I also consistently requested only neutral colors for the items I actually checked, yet my color preferences are NEVER - and I mean NEVER - honored. EVER. In the past few months I've received bright red or orange lipsticks, rainbow colored eyeliners, ridiculously brightly colored shimmery eyeshadows... and all this when I've practically begged over and over in my reviews for them to send only neutral colors. It isn't as if I didn't check enough under the profile to give them a choice of other items to send. They don't pay the slightest attention to that profile or to reviews. What's the point in having the quiz if you're not going to honor it, ipsy? It's a waste of your customers' time and money, and a waste for the brands you're promoting, too, if you're consistently wasting marketing opportunities by sending samples to people who simply aren't interested.
I would also like to mention that there are websites out there that appear to have some sort of agreement with ipsy not to publish a lot of negative reviews and to skew any reviews that appear on the site positively. There is one site in particular - a very popular site dedicated to subscription box reviews and spoilers - that has time and time again either deleted comments I've written or failed to post them. If you write a favorable review it will be immediately published, but if it contains certain negative words or phrases, no matter how innocuous, it will be flagged for review, and half the time will never post in the comments section. Ipsy is the only company I've experienced this with on any review site.
