For one portion at a time, check whether the listing is for a single bar or a multipack of separate bars: the Penguin Original, Rocky Original and Club Mint options compared here are multipacks. Penguin Original offers 14 bars for a household order; Rocky Original has seven smaller 19g bars, while Club Mint is a seven-bar choice when mint flavour matters. Compare the portion information and current allergen label, and decide before checkout whether a substitute would be acceptable.
For lunchboxes, work breaks or sharing, a multipack provides several portions rather than loose biscuits. Ocado lists Penguin Original as a 14-bar pack and Rocky Original as a seven-bar pack, with the bars individually wrapped.
If one bar is the intended serving, compare its weight and per-bar nutrition rather than judging by the whole pack. Ocado lists Rocky Original at 19g and 94 kcal per bar; Sainsbury’s lists Penguin Original at 24.6g and 130 kcal per bar.
A different flavour or recipe may not be an acceptable replacement. Tesco and Sainsbury’s describe substitutions when ordered groceries are unavailable, so review the substitution setting before checkout and check the product delivered.
Start with the number of bars you will receive, then compare one bar as eaten and decide whether a replacement product would work for your order.
| Priority | What to check | Your needs |
|---|---|---|
| Pack format | Check the bar count, weight per bar and whether bars are wrapped separately. Ocado lists 14 individually wrapped Penguin Original bars and seven individually wrapped Rocky Original bars. | I want one bar at a time without mistaking a multipack for a single-bar purchase. |
| One-bar portion | Compare nutrition per bar alongside bar weight. Ocado lists Rocky Original at 94 kcal per 19g bar; Waitrose lists Club Mint at 115 kcal per bar, and Sainsbury’s lists Penguin Original at 130 kcal per 24.6g bar. | A smaller bar may suit my intended portion, but I also want to check what is in the particular product I order. |
| Ingredients and substitutes | Read the current ingredients and allergen statement, set your substitution preference, then check the delivered wrapper. Ocado’s Rocky Original listing also carries a may-contain statement for nuts and peanuts. | If I need a particular recipe or allergen declaration, a similar-looking replacement is not necessarily suitable. |
| Delivery fit | Check whether the pack fits the chosen service’s basket requirements and whether a substitute is allowed. Tesco and Sainsbury’s describe how their grocery services handle unavailable items. | I would rather add a small multipack to a planned grocery order than assume it can be delivered on its own. |
The Penguin Original, Rocky Original and Club Mint products compared here are packs of seven or 14 bars, not loose single-bar listings.
Check the pack count and grams per bar so the quantity arriving matches how you plan to use it.
A substitute can have a different flavour, ingredient list or allergen statement. The compared bars do not have identical declarations.
Decline substitutions if you need the exact product, and inspect the delivered wrapper before eating. Food Standards Agency research on online food purchasing also describes participants with food hypersensitivities double-checking orders and labels.
Delivery services can have basket requirements, so a single multipack may not be enough for the service you intend to use.
Check the requirements for your chosen service before checkout, or add the pack to a planned grocery order.
Penguin Original and Club Mint offer different chocolate biscuit-bar flavours and pack formats in the retailer listings compared here.
Ocado lists Rocky Original as a seven-bar, individually wrapped chocolate-coated shortcake multipack.
These are multipacks of chocolate-covered wafer, biscuit and twin snack bars to consider for a grocery basket. Check each pack format rather than assuming every wrapper contains one bar.

An eight-pack to consider when stocking chocolate-covered caramel wafers. Check the wrapper and per-wafer details if portion size or ingredients affect your choice.

The 14-bar format suits an order intended to provide several separate portions. Check the current wrapper for ingredients and allergen information when it arrives.

This listing is for nine 40g twin-bar packs, not nine single bars. Check whether a whole twin pack or one finger is the portion you intend to compare.
No image available
A five-biscuit pack for an order needing fewer portions. The name identifies a milk and hazelnut variant; check the delivered label if its ingredients matter to you.
The Penguin Original, Rocky Original and Club Mint products compared here are multipacks of 14, seven and seven bars respectively, according to their Sainsbury’s, Ocado and Waitrose listings. Check the unit count if you want just one bar in your order.
Use the weight and nutrition for the serving you intend to eat. Ocado lists Rocky Original at 19g and 94 kcal per bar, while Sainsbury’s lists Penguin Original at 24.6g and 130 kcal per bar; those figures describe individual servings, not the whole packs.
Read the current product information before ordering and check the delivered wrapper before eating; decline substitutions if the exact product matters. Ocado’s Rocky Original listing, for example, includes a may-contain statement for nuts and peanuts, which should not be assumed to apply to every chocolate biscuit bar.
Review the item’s substitution setting before checkout and choose no substitutions if a different flavour would not work. Tesco says it may offer an alternative when substitutions are allowed, and Sainsbury’s says an unavailable item may be substituted.
