For example, I have a One Plus One. Their Carbon Fibre Back Cover costs $14.99 USD. After you put in the coupon code, the price drops to $1.50 which is super cheap. Shipping to New Zealand is $5.87USD for a total of $7.37USD or $9.40NZD.
The screen protectors are very good at protecting your phone.
