Count before comparing
The selected£3.60 TREK offer contains three50g bars,so its derived unit cost is£1.20 per bar. Each£2.90 Grenade or Fulfil offer contains one bar. Looking only at£3.60 versus£2.90 makes the multipack appear dearer without accounting for what arrives. Looking only at£1.20 then calling the bars identical would make the opposite mistake.
Keep the mass difference
TREK’s selected bar is50g,Grenade’s60g and Fulfil’s55g. Three of each would be150g,180g and165g respectively. A lower per-bar price can help a count-based stock plan,but a mass comparison needs the different denominators. Do not infer how filling a bar will be or how long it will last from either number.
A small-stock example
Suppose a buyer chooses a target of five matching TREK bars and holds one. Four more bars are wanted,but the selected retail offer supplies three at a time. Two packs add six,leaving seven total and two above the chosen target. One pack would leave the target unmet. The surplus is an arithmetic result,not encouragement to consume extra bars or a prediction of demand.
A single purchase can still suit the brief
If only one bar is wanted and the buyer does not want extra stock,the selected3-pack is not automatically the practical choice despite its lower unit rate. A suitable single offer may better match that requirement after ingredients,warning scope and actual price are checked. No personal preference or nutrition target is inferred by the tool.
Confirm pack contents again
Retailers can list similarly named singles,multipacks and changed bar sizes. Save the exact product ID and3×50g declaration with the quote. If a substituted item is3×40g or a different flavour,it becomes a new record. The count tool should not silently retain a previous pack’s mass or nutrition when the actual offer changes.
