Dollar Tree should be accepting Buy One Get One (BOGO) FREE Coupons starting this coming week. This is still unconfirmed so don’t shoot the messenger (or start fights with the manager), but my intel is usually good.
If you need to refer to the coupon policy:
Dollar Tree – Terms & Conditions
From what I am told, if you have a $1/1 coupon and a BOGO coupon, then you can buy two items and get both for FREE using coupons.
