Thanks so much to reader @chloe.cosmetics on Instagram for this great tip!
Right now on Groupon HERE, you can purchase a $40 voucher for $15 that you can use via Google Express at Ulta, Walgreens, Costco, L'Occitane, and more (online purchases only; does not apply in-store). IF THAT LINK DOES NOT WORK FOR YOU, once you get to the Groupon page, just search "Google Express" and the deal should pop up. if that STILL doesn't work, try Googling "Groupon Google Express" and it should pop right up. You can also try using code JUMBO3 at checkout for an additional 20% off this voucher (that would bring you down to $12 for a $40 voucher).
This offer is only valid in certain regions of the US, so you need to click HERE and enter your zip code to be sure that Google Express delivers to your area. Also, this offer is only valid for first-time customers of Google Express so if you've purchased things via Google Express in the past, you cannot redeem this voucher.
If you're new to Google Express, it's Google's way to make online purchases from multiple retailers via one site. You must have a Google account to make purchases via Google Express.
I honestly could not remember if I had ever used Google Express before, so when I logged into my Google account (via the Google Express website) and checked my order history, I found that my previous purchases of phone apps from the Google Play Store showed up. But Google Play is not the same as Google Express, so I believe that this does not count as a previous order (Chloe confirmed to me just now that she also has made purchases from the Google Play Store and she was able to use this Google Express voucher for an Ulta purchase. You can see her order confirmation HERE).
I do not claim to know all of the answers about this deal--I'm just passing along as much info as I can. So before you purchase, be sure to check the fine print on both the Groupon page HERE and the help page at Google Express HERE and hopefully you can get the answers you need.

Thanks again for the hot tip and additional info about this deal, Chloe! I really appreciate it.
