A 45-comment community thread on whether cans or bottles sell better in vending produced one clear takeaway: the right answer depends entirely on your location, and operators who assume one is always better are leaving money on the table in half their machines.
Here is the actual economics breakdown, the velocity data operators shared, and the decision framework that tells you which to prioritize at each placement — including why the answer at a gym is the opposite of the answer at a warehouse.
The economics: cans vs. bottles
Cans (12 oz): wholesale cost typically $0.40–$0.65 per unit. Machine price usually $1.50–$2.50. Margin per unit: $1.00–$2.00. Slot efficiency: smaller footprint means more units per shelf column. Key advantage: lower cost if a product doesn't sell, easier to rotate SKUs quickly.
Bottles (20 oz): wholesale cost typically $0.90–$1.40 per unit depending on brand. Machine price usually $2.50–$4.00. Margin per unit: $1.50–$2.75. Key advantage: higher per-unit revenue when velocity is there. Key risk: higher unit cost means slower payback if velocity is low, and more shrinkage from overstock.
When offered at the same price point (which sometimes happens with smart cooler AI pricing), cans may outsell bottles because the perceived value-per-size calculation makes cans feel like a better deal. When bottles are priced at a premium that matches their size advantage, the split tends to be more even.
Location demographics determine the winner
This is the crux. The product mix that works at a 200-person warehouse is different from a 150-member gym. Here is the pattern operators report:
| Location type | Winner | Reason |
|---|---|---|
| Warehouse / manufacturing | Cans | Price-sensitive, high volume, blue-collar demographic values quantity at low price |
| Office (50-200 employees) | Mixed | White-collar demographic drinks both; bottles win for brand-name soda, cans for energy |
| Gym / fitness | Bottles | Post-workout hydration, larger volume preferred, less price-sensitive if product is right |
| Apartment complex | Mixed | Mixed demographics; test 50/50 split for first 30 days then adjust |
| Medical / urgent care | Bottles | Patients hydrating during visits, premium water and still drinks outperform |
| College / student housing | Cans | Price-sensitive, energy drinks and soda cans dominate, volume matters |
Picture the machines paying you while you sleep
That’s the real promise of vending — income that doesn’t cost you your time, and a life on your own terms. VendBuddy turns this guide into a step-by-step plan so you actually build it instead of just reading about it. Start free today.

The only data that matters is your own location's data. Here is a simple 30-day test: stock your machine with a 50/50 split of can and bottle SKUs in similar product categories (e.g., Coca-Cola can + Coca-Cola bottle, Monster can + Monster bottle if your cooler supports it). Set prices reflecting a real margin for both. Track velocity by SKU over 30 days. The format with consistently higher units-per-day wins that column. Do this for each category independently — energy drinks may trend bottle while sparkling water trends can.
After 30 days, shift your split toward the winner. Don't go 100% of anything — variety serves customers who want the other format. A 70/30 split in favor of the winner is usually the right landing point.
VendBuddy's inventory analytics show you daily velocity by SKU so you can run the 30-day A/B test and get clear data without spreadsheets.

Do cans or bottles sell better in vending machines?
It depends on location type. Warehouses and student housing favor cans (price-sensitive, high volume). Gyms and medical facilities favor bottles (larger volume, less price-sensitive). Offices and apartments typically support a mix. Run a 30-day 50/50 split test at your specific location to get real data.
Are bottles more profitable than cans in vending?
Bottles have higher per-unit margin ($1.50–$2.75 vs. $1.00–$2.00 for cans) but require higher velocity to beat cans on total profit per slot. If bottle velocity is at least 1.5x can velocity at the same location, bottles win on slot profitability. Below that, cans produce more reliable income.
What is the best drink to stock in a vending machine?
Across most location types: Celsius energy drink, bottled water, and Gatorade consistently rank as top-3 velocity items nationally. Regional variation matters — see our post on regional bestsellers for location-specific data. Within cans vs. bottles, test both formats for your top-performing SKUs to find which format your specific audience prefers.
