One of Flum's strongest selling points is pricing. Both 50,000-puff flagships come in under $25 — making them some of the cheapest high-capacity disposable vapes on the market when measured by cost per puff. This guide breaks down every current Flum device's price, compares the cost-per-puff value against competing brands like RAZ and Geek Bar, and helps you figure out which Flum gives you the best bang for your dollar.

Cost-Per-Puff — Why the 50K Models Win
The price difference between the cheapest Flum ($22.99 for Mello 20K) and the most expensive ($24.99 for either 50K) is only $2. But the puff-count difference is massive — 50,000 vs 20,000. This means the 50K models deliver 2.5x more puffs for less than 10% more money.
If pure value is your priority, the 50K models are the clear choice. The Mello 20K still makes sense if you specifically want the themed editions (City Series, Floral Delights, Valentine, Christmas) — those are Mello 20K exclusives not available on the 50K. And the UT 25K is the most compact option if portability matters more than per-puff cost.
Flum vs Other Brands — Cross-Brand Price Comparison
This is the comparison you will not find on any brand's own website. Here is how Flum's pricing stacks up against the top-selling brands at VapesOnlineShop in the 50K and 20-25K puff tiers:
50,000-Puff Tier
| Device | Brand | Puffs | VOS Price | Cost / 1K Puffs |
|---|---|---|---|---|
| Float Mello Pro 50K | Flum | 50,000 | $24.99 | $0.50 |
| UT Bar Pro 50K | Flum | 50,000 | $24.99 | $0.50 |
| Lost Angel Mate 50K | Lost Angel | 50,000 | ~$26-28 | $0.52-0.56 |
| RAZ VUE 50K | RAZ | 50,000 | ~$27-29 | $0.54-0.58 |
20,000–25,000 Puff Tier
| Device | Brand | Puffs | VOS Price | Cost / 1K Puffs |
|---|---|---|---|---|
| Mello 20K | Flum | 20,000 | $22.99 | $1.15 |
| UT Bar Pro 25K | Flum | 25,000 | $23.99 | $0.96 |
| Geek Bar Skyview 25K | Geek Bar | 25,000 | ~$25-27 | $1.00-1.08 |
| RAZ DC 25K | RAZ | 25,000 | ~$24-26 | $0.96-1.04 |
Flum consistently comes in at the lower end of the price range in both tiers. The 50K models in particular offer about 10-15% better per-puff value than RAZ equivalents and roughly 50% better than Geek Bar's 25K. This is Flum's clearest competitive advantage alongside the UT 50K's dual-flavor switching.
Which Flum Device Is the Best Value?
| Your Priority | Best Pick | Why |
|---|---|---|
| Absolute cheapest per puff | Either 50K model | Both at $0.50/1K puffs — tied for cheapest in our entire store. |
| Lowest upfront cost | Mello 20K ($22.99) | Cheapest Flum device if you want to try the brand without committing to $25. |
| Best features per dollar | UT Bar Pro 50K ($24.99) | Dual-flavor switching + 40 flavors + 50K puffs for $24.99. Most feature-rich Flum at any price. |
| Best mid-range balance | UT Bar Pro 25K ($23.99) | 25K puffs with Turbo Mode for $1 less than the 50K. Good if you don't need dual tanks. |

Frequently Asked Questions
How much does a Flum vape cost?
At VapesOnlineShop, Flum devices range from $22.99 (Mello 20K) to $24.99 (Float Mello Pro 50K and UT Bar Pro 50K). The UT Bar Pro 25K is $23.99. Local store prices may vary and are often higher due to retail markup.
Is Flum cheaper than RAZ?
Yes, in the 50K-puff tier. Flum's 50K models cost $24.99 at VOS (about $0.50 per 1,000 puffs), while the RAZ VUE 50K typically costs $27-29 ($0.54-0.58 per 1,000 puffs). That is a 10-15% savings with Flum. In the 25K tier, Flum and RAZ are priced similarly.
Why are Flum vapes cheaper at VOS than at local stores?
Online retailers like VapesOnlineShop buy directly from manufacturers in bulk and have lower overhead than physical stores. Local vape shops and smoke shops need to cover rent, utilities, and staff costs, which typically adds $3-8 markup per device. Gas stations and convenience stores often have the highest markups.
