A shopper takes a screenshot of your Black Friday banner and sends it to a friend.
“Is this a good deal?”
Her friend replies, “On what?”
There goes the first half of the media budget. The second half is currently looking for the asterisk.
The screenshot is a useful place to start because it travels without your landing page, your brand film or the nice person on the chat widget. It contains exactly what a shopper saw and almost none of what the campaign team meant.
In November 2026, Boston Consulting Group reported that 54% of respondents in its year-end sales study trusted advertised prices at these events. The study surveyed 10,220 adults across ten markets in Europe, North America and Australia. The finding gives us a reason to examine how a shopper verifies value before asking how to make the number on the banner bigger. BCG’s 2026 year-end sales study
One pair of headphones and three offers
Imagine a $100 pair of wireless headphones with a $55 variable cost before the promotion. We can spend up to $10 per qualifying shopper on the offer itself. We can make the discount immediate, put an extra benefit alongside the purchase or save the incentive for the next order. Any incremental programme fees, delivery costs or support costs must be included in the relevant arm. These are illustrative numbers.
| What the shopper sees | Offer cost to the brand | When it earns its place |
| Pay $90 today. | $10 on each qualifying order. | Test it when immediate conversion is the goal and price is a credible barrier. |
| Pay $100 and get two cinema tickets. | Assume $10 for both tickets, including fulfilment. | Test it when the audience values the experience and can actually book it. |
| Pay $100 and get $10 off an eligible next order within 45 days. | Up to $10 per customer, depending on redemption, before any fees. | Test it when the brand sells something customers are likely to need again within that window. |
The cinema tickets are where the conversation gets interesting. Two tickets in a city with good cinema coverage can feel like a Friday night already sorted. Two tickets with no convenient venues, narrow time slots and a long booking flow can feel like homework with popcorn.
The $10 credit has a different problem. A headphone buyer may be done shopping in the category for months. The offer becomes more credible if there is a natural next purchase, such as a compatible travel case, and the terms let the customer use it on that purchase. Check the price of that case before you print the offer. A $10 reward that requires a $90 order will have a very different audience.
Give the offer the screenshot test
First, crop the offer to the size of a phone screen. Then hand it to someone who did not work on it. Ask them to answer four questions without opening a second page.
- What do I pay today?
- What exactly do I get and when?
- What might make me ineligible?
- If I have to claim it, what is the first step?
Put material constraints where the shopper makes the choice. A cinema reward may depend on location, participating venues and booking windows. A future credit may depend on a minimum spend. If the gift can run out, say so up front. Use a short terms link for detail and keep the condition that changes the offer next to the promise.
Run the same test with customer support. If a service agent needs a spreadsheet to answer “Can I use this on Saturday?”, the shopper is probably going to need help too.
Make the decision on contribution
At 100 orders, the headphones generate $4,500 in contribution before any offer cost or other costs excluded from this simplified example. A $10 markdown brings that to $3,500 on the same 100 orders. The assured gift has the same simplified contribution at that volume if all 100 gifts cost $10 each to deliver. A next-order credit needs a longer measurement window because the first and second order both matter.
Use comparable audiences, stores or regions, with a control group where feasible. Keep product availability, placement, shipping and timing as similar as possible. Compare contribution per eligible shopper across groups by subtracting variable product costs, incremental fulfilment, reward costs and any extra support or media spend from net sales after discounts. Subtract only costs that are still outside net sales so a redeemed credit is counted once. Read the immediate offers at the close of the sale and read all arms again after the future reward has had time to expire and returns have settled.
The main question is how many purchases the offer added, how much contribution they generated and what happened after the rush. A credit redeemed by customers who were already going to reorder can post a lovely redemption rate while quietly paying for sales the brand would have had anyway. A comparison group is what helps separate those outcomes.
Track claim completion and fulfilment exceptions alongside contribution. Check how often customers qualify but fail to receive the reward, how many contact support and how many attempts are duplicates. Every one of those numbers can explain why an attractive offer underperforms.
If you’re planning a promotion around a margin target, bring one product, one audience and one budget to the discussion. RewardPort can help map the offer, the claim process and the measurement plan before the banner goes live. RewardPort sales promotions
Frequently Asked Questions
Can an assured gift be easier to trust than a discount?
It can be easier to verify if the shopper can see exactly what they receive and the eligibility and booking terms are clear. Test the response with the audience and the actual offer.
Should the value of a gift match the size of the discount?
Match the planned cost to the brand for a fairer experiment. Test perceived value separately. The customer’s valuation depends on relevance, convenience and confidence that the gift will be delivered.
When is a next-purchase reward a good fit?
When there is a plausible reason to buy again within the redemption window and enough expected contribution to justify the offer. Look at the category’s purchase cycle before setting expiry.
What should we measure beyond sales on the day?
Measure incremental contribution, returns, claim completion, support contacts and verified repeat purchases. Use a comparison group to estimate whether repeat purchases were added by the promotion.
What belongs on the first screen of an offer?
Show the amount due today, the specific benefit, the timing, and any limit or condition likely to change the shopper’s decision.
