Nic salt e-liquid bottle lifespan and cost comparison

A 30ml bottle of nic salt e-liquid lasts me about two weeks, which costs around $15 to $20; compared to freebase, it’s pricier upfront but I vape less since the nicotine hits faster, so my monthly expense stays similar, around $30 to $40, plus the bottle’s small size fits easily in my pocket.
