I smoked a little less than a pack a day and started saving after 2 weeks. Look a my banner below. I've Spent less than 500 on vaping in the last year. I just stick to a budget of 40-50 per month avg. however I started diy after 3 months and then the next month upgraded my mod. The next month upgraded to an rba. If you only get what you need and don't start collecting mods you'll be fine.
