A delivery fee is easy to see at checkout. The real cost of collecting an order is less obvious: a return trip can involve fuel, wear on your vehicle, parking, and time you could have spent elsewhere. Whether delivery is worth it depends on your inputs, not a universal rule.
Start with the whole journey
If a shop is 15 km away and you will drive home again, the trip is 30 km, not 15. Check whether you're making a dedicated journey or combining the pickup with a trip you were already going to make. For an extra stop on an existing journey, comparing only the additional distance can be more realistic.
Estimate what collection costs
For a dedicated collection trip, one practical model is:
For fuel, multiply the total distance in kilometres by consumption in litres per 100 km, divide by 100, and multiply by the price per litre. Vehicle wear is an estimate for tyres, servicing, depreciation and other distance-related costs. Your time valuation is optional: setting it to zero focuses on immediate cash outlay.
Worked example in rand
Suppose you're considering collection from a shop 15 km away. Your car uses 8 L/100 km; fuel costs R23/L; wear is estimated at R1.20/km; the average driving speed is 40 km/h; pickup takes 20 minutes; and you value your time at R100/hour. Delivery costs R120.
| Item | Calculation | Estimate |
|---|---|---|
| Return distance | 15 km × 2 | 30 km |
| Fuel | 30 × 8 ÷ 100 × R23 | R55.20 |
| Vehicle wear | 30 × R1.20 | R36.00 |
| Driving and pickup time | 45 + 20 = 65 minutes × R100/hour | R108.33 |
| Estimated collection cost | Fuel + wear + time | R199.53 |
| Delivery fee | Quoted fee | R120.00 |
In this illustrative scenario, delivery is about R79.53 cheaper when you value your time as described. If you count only fuel and wear, collection is about R91.20, making it cheaper than delivery by R28.80. The conclusion changes because the assumptions change.
When collection may still make sense
- You're already passing the shop and the extra distance is minimal.
- Delivery timing is inconvenient or uncertain.
- The item is urgent, fragile or easier to inspect in person.
- You enjoy the trip or don't want to assign a monetary value to your time.
What this calculation leaves out
Delivery delays, risk of damage, failed deliveries, insurance and environmental effects may matter even though they are not priced into this simple comparison. Don't count the same cost twice: if your wear-per-kilometre estimate already includes fuel, remove the overlap.
