Aldi vs Lidl: Germany's Discounters Are Fighting an Ad War Over App Discounts
Aldi Süd has gone on the offensive with a 'Günstig ohne Bonus-App' campaign that mocks rivals Rewe, Lidl and Edeka for hiding their best prices behind loyalty apps — and Lidl has fired back with a comedy social spot. It's a rare open ad war among German discounters, and brand experts reckon Lidl is coming out on top.
Aldi throws the first punch
Since late July, Aldi Süd has run a coordinated offensive across TV, radio, social and out-of-home under the banner 'Günstig ohne Bonus-App' — 'cheap without a bonus app'. The message is pointed: while rivals Rewe, Lidl and Edeka increasingly gate their best deals behind loyalty apps, Aldi says its prices are simply low for everyone.
It's a classic challenger move: find a genuine consumer irritation — the friction of scanning, downloading and data-sharing just to get a fair price — and turn it into a moral high ground. Aldi effectively framed app discounts as a two-tier checkout, or a 'Zwei-Kassen-Gesellschaft'.
Lidl hits back
Most of the named rivals stayed conspicuously quiet. Lidl was the exception. Rather than a defensive statement, it answered with a comedic social spot — an 'urkomischer Werbefilm' — that turned Aldi's swipe into a setup for its own joke, then kept escalating as both sides 'legten nach' into late August.
That instinct matters. Silence can read as guilt in a public spat, but a heavy-handed rebuttal can validate the attack. Lidl chose the third path: humour, which lets a brand engage without looking rattled.
Why experts think Lidl came out ahead
German brand experts have largely scored the exchange for Lidl, arguing its agile, funny response outmanoeuvred Aldi's straighter attack. The commentary in the trade press has run to headlines like 'Lidl führt Aldi im Preiskampf vor' — Lidl showing Aldi up in the price war.
Our read at Marketing Minute: this is comparative advertising's oldest trap. When you name a competitor, you don't just attack them — you invite them onto your stage and hand them a right of reply. The attacker sets the topic; the responder, if quick and witty, can seize the tone.
The bigger lesson on attack ads
The underlying insight was sound. App-gated pricing is a real and growing friction for shoppers, and Aldi was smart to name it. The misstep was pointing at specific rivals rather than the practice itself — turning a category argument into a personal duel.
For any brand tempted by a comparative campaign, the test is simple: are you confident you'll win the exchange, not just the opening shot? If a rival can flip your attack with a single funny reply, you've built them a platform, not a trap.

Comparative advertising is the riskiest move in the book. You pick the fight, but you don't control the punchline. Aldi found a real consumer nerve in app-gated pricing — yet by naming Lidl directly, it handed a nimble rival the perfect opening.
