I won this voucher in a recent contest for OM vapors and it can only be applied toward shipping and cannot be combined with an existing promotion. I honestly have no plan on using it as it doesn't seem worth it, not to sound ungrateful but their cheapest juice is $10 for 30ml and already free shipping for orders of $25+ Anyway...... if you'd like it just leave a comment first to post for it will receive the code via PM
