With the pricing error for the 70-200mm F2.8 IS II lense,
"We would like to apologise but the item you have purchases there was a price error.
We will be refunding your order back to your preferred payment method and would like to give you a $10 off next purchase. Promo code: NW10PROMO"
I tried chalking up to $22 worth of accessories, it worked.
Choose only phone accessories which applies free shipping.
When going through paypal payment, you need to change it from $0.00 to $0.01 in order to be processed.
Any minimum spend?
