> MonsterDealz

MonsterDealz is a German deal site. A small editorial team posts the discounts, coupons, cashback offers and pricing errors it finds, and checks each one against Idealo, Geizhals and Amazon before publishing. Every deal shows the current price, the reference price and the actual saving, and the post says so plainly when a "deal" turns out not to be one.

The site works as a feed, not a search box: new offers appear at the top of the homepage all day, sorted into around 40 categories from electronics and mobile contracts to household, food and travel. Next to the editorial deals there are User Deals submitted by readers and reviewed before they go live, Bonus Deals (bank, broker and app sign-up promotions that pay out as Amazon vouchers), a shop directory, and a magazine section with buying guides on Black Friday, Prime Day and similar events.

The free iOS and Android apps carry the same feed with push notifications for new deals, a favourites list, comments and private messages, plus M-Coins, a points system readers can trade in for Amazon vouchers. A browser extension for Chrome and Firefox turns the RSS feed into desktop notifications, and a newsletter goes out twice a week.

Independent and online without a break since 2009, with more than 100,000 deals published and an active comment community. Affiliate links are used and disclosed. Note that the site itself is in German.
