You'll be charged for your Refreshments membership in the second month, after your trial kit has shipped. You'll be billed on the last day of the month (unless you cancel or make changes by 12 p.m. PT).
You can locate your next billing date and how to make changes by going to IPSY.com and clicking on Account > View Membership > Refreshments.
Note: Refreshments is a separate membership from your monthly beauty subscription, so you'll see a separate charge.
