Once you reach a tier, it will be valid for 12 calendar months. For example, if you join in August 2018 and reach tier 1 by October 2018, you will receive tier 1 benefits until October 2019. If you qualify for tier 2 by November 2018, you will receive tier 2 benefits until November 2019. If you do not purchase in the 12 months you are in any tier, you will lose your Tier status after 12 months. Returned orders, purchases of e-gift certificates, shipping costs, taxes and duties for international purchases will not be included in your Bar Bucks total.
