I need to buy several 5 packs of 1.5 & 2.0 ohm Smoktech dual coil replacement cartomizers for my 3.5 DC tanks?? I like them with 2 predrilled holes, and i need a good price (discount code if possible) without sacrificing quality.. My mother just had back to back surgeries removing 2 separate stage 1 lung cancer from both lungs, i am her only caregiver so I just dont have a lot of time to shop around so i figured i would ask & see if anyone already knows where I can go for these?? Where should i go & where should i avoid? Thank you for any help andme Many Blessings to you and yours! Kelly H.
