Mumias sugar 2 kg: Naivas ends lower as Carrefour’s price rebounds

The lower-priced retailer for Mumias sugar 2 kg changed during ShelfSight’s 12–19 October 2026 comparison. A temporary dip at Carrefour ended with its price back at KES 302, while Naivas closed at KES 289.

That left Naivas KES 13 lower across the two tracked listings on 19 October. Earlier in the comparison, Carrefour had been lower.

Carrefour returned to its starting price

Carrefour’s observations show KES 302 on 12, 13, 14 and 15 October. The price then appears at KES 279 on 16, 17 and 18 October, before returning to KES 302 on 19 October.

The latest day-to-day movement was therefore an increase of KES 23, or 8.24%, from the 18 October observation.

Across the full 12–19 October comparison, however, the net change was zero. Describing the latest rebound as a weekly increase would miss the earlier dip.

Naivas held its lower price

Naivas’s tracked listing was KES 305 from 12 through 15 October. It then moved to KES 289 on 16 October and remained there in every returned daily observation through 19 October.

That is a net weekly reduction of KES 16, or 5.25%.

On 16–18 October, Carrefour’s KES 279 listing was KES 10 below Naivas’s KES 289. By 19 October, the order had reversed: Naivas was KES 13 below Carrefour.

A reminder to recheck recent prices

The evidence contains 16 observations across the two listings, with a record for each retailer on all eight dates. The closing observations were captured around 08:33–08:34 EAT on 19 October.

The records do not identify a promotion or explain why either price changed. They show how quickly a recent comparison can become outdated.

A KES 13 item-price gap should also be weighed against delivery, travel and the cost of other groceries. It is not a finding that one retailer is cheapest for the complete basket or across Kenya.
