Thanks to reader @boricuasmiles on Instagram for this tip!
Makeup Geek is having sale that ends tonight (6/19). Enter code STOCKUPXVN on the Makeup Geek website for 15% off sitewide (excludes MannyMUA Palette pre-orders). Shipping is calculated in cart.
I just tested this with an item from the sale page and it worked. I added a $5 blush pan to my cart, and when I entered the code it went from $5 to $4.25 + $1.99 shipping.
Thanks again, @boricuasmiles, for the great tip!
