I applied a 5% coupon, and suddenly the free shipping off was revoked, which ultimately made the transaction cost more, rather than saving me money. I only bought 1 item, a (physical, not e-) book. After applying the coupon (5% off), the cost was under the $35 threshold, so an additional $4.99 cost was added, for the shipping. But I couldn't figure out how to remove the coupon
