How to compare JB vs SG grocery prices fairly

Start with the same product and pack size

A fair comparison begins with the same brand, variant, and pack size. If the pack differs, compare the unit price and treat the row as a benchmark rather than an exact match.

Use converted price and unit price together

The converted JB price shows the headline S$ equivalent, but unit price is what keeps bulk packs and bundles honest. A lower sticker price can still be a weak deal if the pack is smaller.

Once the unit price looks attractive, use the basket planning guide to decide whether the item still makes sense after trip cost, weight, freshness, and review status.

Check review status before trusting savings

Rows marked as needing an SG check should not be used as savings claims. Use them as leads for further checking until both sides have credible source context.

The full rule set is explained in the methodology.
