Don't let people discourage you on your savings goals. Shoot for them and if you only get "close", it's a win/win. You will always invest more initially than it takes to maintain vaping supplies. Let me share what is realistically possible.
For my wife and I, we started this year already owning a SS ZMax2 and a modded maxi roughstack, 4 18650 IMRs, 1 AGA-T, 1 IGO-L, 1 Chalice.
Investments this year: x2 K100s, x8 batteries, x2 evolv kicks, x2 IGO-Ls, x2 AGA-Ts, enough nic/pg/vg and flavor for our favorite recipe to make 950 ml of juice, and enough wick and wire to easily last the year.
Total investment this year to date: $270
So we each have a PV and a back up, 12 batteries, 7 rbas, wick and wire to last the entire year, and enough juice to last 10 months.
Cost to replace wick n wire for another year, $20.
Cost to replace Juice to last another 10 months, $50.
Total expected investment this year <$400
Total savings per your numbers $2800 per year
Get dependable gear including backups, use co-ops when possible.
Avoid the I-must-have-the-newest-xyz-every-time-i see-something.
Replace consumables as you need to, buying in bulk for savings when possible.
Smoking was costing you $8.77 per day.
Budget $1 a piece per day for vaping materials and save ~$2500 per year
