Product comparison: why delivered cost beats unit price

What to take away

Three quotes side by side show what a price list hidesthe add-on charges, not the unit price, decide the winner.
Lay every quote out in the same columns before you read the totals.
Record reprint and replacement terms beside the delivered total, because a spoiled run costs you twice.
Three suppliers are usually enough to show the spread.
File the quotes and your scoring notes after ordering, so a reorder starts from evidence.

Three tote bag quotes side by side

The middle quote wins on delivered cost. For 500 branded cotton tote bags, the three quotes were £2.10, £2.35 and £2.60 per unit. With setup, one-colour print and carriage added, the delivered totals were £1,340, £1,290 and £1,355. The figures are illustrative, not market data.

Delivered cost comparison

Quote B

Unit price: £2.35
Delivered total: £1,290
Cheapest unit: No
Cheapest delivered: Yes

Quote C

Unit price: £2.60
Delivered total: £1,355
Cheapest unit: No
Cheapest delivered: No

Quote	Unit price	Delivered total	Rank on unit price	Rank on delivered cost
First	£2.10	£1,340	Cheapest	Second
Second	£2.35	£1,290	Middle	Cheapest
Third	£2.60	£1,355	Dearest	Dearest

Read the two rank columns together. The first quote leads on unit price but falls to second place once setup, print and carriage are counted, so its extras must be the largest. That gap stays hidden until each quote is split into its separate lines, which is why the split comes before any scoring.

Why the cheapest unit price lost

The cheapest unit price lost because its extras were the biggest. A low unit line tells only part of the story. Ask each supplier for the unit cost, decoration, setup, carriage and any artwork fee as separate lines, then add them up yourself.

Check the quantity breaks before you trust any figure. A price that only holds at 1,000 units is not a price for a 500-unit order, and a quote for a different quantity is a different order. Ask every supplier to price the same 500, then ask separately what a larger run would change.

Reprint, spoilage and lead time

Spoilage terms can change the winner as much as price does. Print runs go wrong, and a supplier that replaces faulty items at its own cost is worth more than one that charges again. Write the replacement rule next to the delivered total.

In the tote example, the second quote only stays ahead if its terms hold. If that supplier charges for a reprint and a rival replaces faulty bags free, the order of the three could shift. Ask in writing who pays when part of the run is spoiled, and compare the answers with the quality checklist.

Lead time works the same way, because a late order has no residual value. Ask each supplier for the production date, the dispatch date and the courier. A quote that arrives later than the others can still be the right buy, but only if you have priced the delay.

The Office for National Statistics publishes volume of production data for UK manufacturing, which helps you judge whether a quoted lead time is realistic.

Claims and artwork on the bag

A recycled or organic cotton claim on the bag is advertising, so ask for the certificate, test report or supplier declaration behind it. If it cannot be produced, score the product down or rule it out.

For organic cotton, ask whether the certificate comes under the Global Organic Textile Standard (GOTS), and for recycled content the Global Recycled Standard. Misleading claims can be referred to Trading Standards through the ASA's referrals process.

Verify claims and IP

Ask for certificate, test report or declaration
Score down or rule out unproven claims
Confirm who owns logo, character or slogan
Check GOV.UK intellectual property guidance
Avoid lookalike items that copy protected designs

If the bag carries a logo, character, slogan or licensed design, confirm who owns what before printing. The Intellectual Property Office publishes a collection of intellectual property legislation, manuals, guidance and notices on GOV.UK.

Supplier catalogues often contain lookalike items, and a product that copies a protected design creates risk you carry, not the supplier. Settle this before you accept a quote, and read the advertising rules for the claim wording.

How many quotes to ask for

Three suppliers is usually enough to expose the spread on price and lead time. Two makes it hard to tell whether a quote is competitive, and five or more slows the process without changing the decision. The tote example used three for that reason.

Send each supplier the same specification: product, colour, quantity, decoration, print area, artwork, packaging and address. If you are still building the shortlist, the supplier comparison guide and the round-up of best providers in England show how suppliers differ. The review methods weight price against delivery and quality.

Records to keep after the order

Keep four things once the order is placed. Those records let you reorder quickly and show why you chose a supplier if anyone asks. Without them, the next order starts from memory rather than from evidence.

Every quote received, including the ones you rejected
Your scoring notes with delivered cost, lead time and replacement terms

Common questions

Can I use the tote figures in my own budget?

No. They are illustrative, not market data. Use the method instead: send one specification to three suppliers and build your own table from the quotes that come back.

Should the lowest delivered cost always win?

No. If the cheapest supplier cannot hit your date, cannot evidence a claim or will not replace faulty stock, the next quote up is the better buy.

Does a sample settle the comparison?

A sample confirms print quality and colour, but it does not confirm lead time or spoilage behaviour. Use it as one input, not the deciding vote.
