Free stickers by mail is the most underrated category in the free-sample world. The economics are absurd in your favor: a sticker costs the brand maybe $0.30 to print and $0.50 to mail, total cost under $1, in exchange for ongoing visibility every time you put it on a laptop, water bottle, car bumper, or notebook. Brands have figured out that a sticker is a $1 mobile billboard, and the result is hundreds of brands running ongoing free-sticker programs through their websites.
What's listed below is the current set of free stickers FreebieAgent has scored: bike brands (Subrosa, Prevelo), outdoor brands (BackCountry, Henry Repeating Arms), advocacy organizations (climate, anti-trafficking, ADA awareness), and a long tail of indie brands and causes. Most are forms (name, address, sometimes "tell us about yourself") and the sticker arrives in 2-6 weeks. A handful (Disney's health tracker, BMX lifestyle brands) include extras like pins or small kits.
Free shipping. No purchase required. The stickers are real and the programs are mostly perpetual rather than wave-based; once a brand commits to giving away stickers, they tend to keep doing it.
Stickers are the cheapest, lowest-friction free-stuff category, perfect for kids learning to fill out forms, for collecting designs for water bottles or laptops, or just for testing whether free-sample programs actually work before committing to higher-effort categories. The list below refreshes weekly as new brands launch sticker programs and older ones close out. If you want a steady drip of free stickers in the mail, sign up for 10-15 of the programs listed here over a single afternoon; the envelopes will start arriving within a few weeks and keep showing up for months.
