Nh coupon laws
This law does not apply to season passes or non-refundable coupons. For example, a company may want to test the amount of a coupon promotion within a limited area.
If you have no paid anything for the coupons, my opinion would be that they expire pursuant to the date noted on the coupon. Occasionally, stores may use the words "manufacturer coupon" on a coupon that's technically a store coupon, and this is where things can certainly begin to get a little confusing for shoppers!
One store in our area will take any manufacturer coupon, even if it says 'Redeemable at store name ' with a different store's name printed on it. Failure to do so could result in coupon fraud.
