Slims E-Juice is the best juice provider I have ever had the pleasure of purchasing from, bar none. I switched to an online realtor after my local B&M shop started charging absolutely ridiculous fees per ml of juice. This wasn't their fault, it was the government's, but I couldn't justify spending that amount of money anymore. I got recommended to Slim's through Reddit and don't intend to shop anywhere else ever again. Slim is the real deal.
Slim will find any excuse to give you a ridiculous discount. I've been a shopper for a couple months and have gotten so many 50% offers, it's amazing. The base prices without the discount are much lower than my local B&M shop was before the fees, and with the discount I can't understand how they make a profit. The quality of the juice is impeccable. I vape only one flavor (skittles) and was nervous about switching shops because other B&M shops near me can be inconsistent. This juice was perfect and I bought 32oz of it.
My girlfriend does not have a set juice that she loves, she enjoys variety. She opts for the sample packs so she can get 5 bottles of 10ml juice at once. While not every flavor is to her specific tastes, she raves about the quality. She greatly prefers all of Slim's flavors to those from the local stores.
Slim's is the tops, absolutely fantastic quality AND price.
