This deal will only work for people who haven't had Birchbox for the last 3 month and/or are new to Gilt City. They have a deal for a one year Birchbox subscription and $25 in credits for the Birchbox store for $99 ($135 value) (click on the "National" category to find it). But if you sign up for Gilt City using an invite link (here's mine) you'll get 25% off your first order. If you already have a Gilt account, but have never bought from Gilt City, you can use the code welcome20 to get 20% off your order. You can also get an extra 4% cash back using Ebates.
According to my calculations, this makes Birchbox about $6.50 a month, depending which code you use, instead of the usual $10 you would pay if you were doing it on a monthly basis. Plus you get all those credits.
Ugh, this is really tempting. I was planning to drop Ipsy (getting bored with it) in favor of Birchbox in September once I'm working full time again (I got a job!). But this deal ends July 28. Is that money worth more to me now or later?
