I got that e-mail about them closing as well, but I didn't see anything about it on their website. There were different coupon codes for flavors, juices and DIY equipment but I didn't see any codes for hardware, nicotine, PG or VG.
The e-mail address it was sent from seemed off, but I didn't pay attention to previous promo e-mail's address so it might have been fine. Even so, my spidey sense was tingling and I deleted the e-mail.
From what I remember, the sale dates and promo codes in the e-mail match what they have listed on their FB page. However, the FB page is calling it a 'Surplus Liquidation Sale'. I wonder if there was a screw up somewhere.
