Is a discount voucher for a supermarket or well-known brand shared on Facebook real?
Rarely. Brand impersonation voucher posts are widely used to harvest personal data, spread malware, or grow fake pages.

Explanation
Fake voucher and discount posts impersonating supermarkets, fast food chains, and major retailers are among the most widely shared fraud content on social media. They typically promise a substantial discount in exchange for sharing the post and completing a short survey — which collects your personal data — or clicking a link that installs adware or redirects to a subscription sign-up page. The genuine brand has nothing to do with the post. Real supermarket and retailer promotions are published on the brand's official verified social media page or official app. Before sharing any voucher post, check it is from the brand's verified official page and that the offer is listed on their official website.
Common red flags
- Voucher post asks you to share before you can access it
- Post is from a page that slightly mimics the brand's name but is not verified
- Survey required to receive the discount
- Offer is unusually generous — large amount off or free products
- Link in the post leads to a domain unrelated to the brand
What to do now
- Verify any promotion on the brand's official website or app
- Do not share voucher posts from unverified pages
- Report fake brand impersonation posts to Facebook and the brand
- Avoid surveys linked from social media posts promising prizes
