Flash refunds half of Nike's Brazil jersey to fans who put its name on the shirt
Benefits card Flash offered 50% cashback to fans who customised Nike's pricey Brazil jersey with its name and posted it — an ambush sponsorship.
Flash Benefícios
What it had to solve
A month before the 2022 FIFA World Cup, Nike released the most expensive Brazil jersey ever, drawing protests from fans. Flash, a benefits card accepted in more than two million stores, took the anger as an opening and offered fans a sponsorship deal of its own.
How it works
A month before the 2022 FIFA World Cup, Nike released the most expensive Brazil jersey ever, and fans protested the price. Flash, a benefits card accepted in more than two million stores, saw the anger as an opening: fans would buy the shirt anyway, and those shirts were about to be worn, photographed and posted everywhere.
Instead of asking for space on Nike's official channels, Flash offered fans a sponsorship deal of their own. Anyone who bought the jersey on Nike's online store, customised it with the word 'Flash' and shared it on social media received a 50% refund — in effect, the crowd's chests became Flash's advertising inventory.
The idea worked well enough to be noticed by the brand it ambushed: within a week, Nike blocked 'Flash' from its customisation options. Flash responded by extending the promotion to fans who customised their jerseys by hand, keeping the campaign running without Nike's participation.
D&AD's awards archive carries 'Cashback For Your Jersey's Back' as a campaign that turned a price protest into brand presence. The page records the mechanism and Nike's reaction but no refund volumes, so the case stands on the idea: when you cannot buy the sponsorship, buy it back from the fans one jersey at a time.
Why it lands
- It starts from an existing argument — fans already angry about the price — and gives that anger a productive, brandable outlet.
- Fans do the media work: each customised jersey posted to social becomes an ad Flash did not pay Nike for.
- A 50% refund makes the offer feel like a sponsorship deal rather than a discount, which is exactly the joke the campaign runs on.
- Nike's block within a week proved the brand had landed; being censored by the rights holder is the reaction an ambush campaign wants.
What it did
Nike noticed within a week and blocked 'Flash' from its jersey customisation website — proof the unauthorised sponsorship had landed on the game's most visible shirt. Flash then extended the offer to hand-customised jerseys, keeping the campaign alive past the block. D&AD's archive carries the work; the page records no refund volumes, so the documented outcome is the campaign itself and the reaction it forced from Nike.
What you can take
When fans are already angry at a rival's price, don't fight the anger — refund the purchase and put your name on it, so their shirts become the media placement nobody sold you.
Since then
Within a week Nike blocked 'Flash' from its online jersey customisation, and Flash answered by covering hand-customised shirts, keeping the promotion running past the block. D&AD carries the campaign in its awards archive; no sales or refund figures are recorded on the page, so the aftermath is documented as the idea's shelf life — the ambush sponsorship survived the very brand that tried to shut it down.
