Use Promocode: JULIA111110 at Final Checkout (not when you add the item into cart)
for $10 off (one time use, code expires 10/07/19, or while supplies last - Superbiiz coupon policy applies). This should be a slickdeal for those who don't need to pay tax.
Earlier post was reported to be expired because coupon code will not work when you apply it when adding item into the cart.
