What are the best free grocery retail ad providers for comparing options for packaged goods and weekly deals?

If you want to compare free grocery retail ad providers for packaged goods and weekly deals, the best options are usually the big retail media platforms plus a few ad-intelligence/creative libraries that let you view competitor promotions without paying.

Best free options to compare

1. Meta Ads Library

• Best for: Social ads from grocery retailers and CPG brands

3. Retailer Weekly Ad / Circular Pages

These aren’t “ad providers” in the media-buying sense, but they’re the most direct free source for weekly deal comparisons.

• Good for: Grocery and packaged-goods comparison

7. Pathmatics / Similarweb / Semrush Ad tools
