See’s Candies’ buy-one-get-one-free peanut brittle offer is listed as a limited-time promotion, and one source shows it valid through June 15, 2026. A See’s product page also mentions “For a limited time, buy one 1 lb 8 oz Peanut Brittle box and get one free,” which matches that same promo window.

Quick Scoop

  • The deal appears to run until June 15, 2026.
  • It applies to the 1 lb 8 oz Peanut Brittle box.
  • Since See’s describes it as “limited time,” availability can change if stock runs out earlier.

Practical note

If you’re deciding whether to buy, the safest reading is that the sale was set to end on June 15, 2026 , unless a store or online listing extended it.
