Don't forget the 30% off sale at Totally Wicked today only. I picked up 10 510 atty's for just under 63.00 with shipping. I know some don't like TW but this is the second time around I am buying atomizers from them on a 30% sale. The first batch were great. I still have one unused and the other 4 are still rockin after almost two months. Just a heads up for those looking for a bargain...
