I know it's frustrating sometimes when I post about deals that have a very short shelf-life, but Zoya just posted this on their Instagram page 36 minutes ago (as of the time of this post). So I'm bringing it to you as quickly as I can!
RIGHT NOW through 9PM EST tonight (12/9), get three full-size polishes of your choice + a Big Flipper Remove+ for $20 with free shipping. Just enter code TWTY at checkout on the Zoya site to get this deal. This is a nice value considering that three polishes + a Big Flipper would normally cost around $40 plus $6.95 for shipping.
Thanks again, @swatchalittle, for this tip!
