You need to buy these cards instore only. Not a huge amount of them around, only 8 I believe, and none in Auckland. Still this is a good grab if you do have one in your town.
Lincraft regularly do 40 or 50% off storewide so a great stacking deal here.
You can use the gift card online, so you could travel to the store grab some cards then use them online down the track.
Lincraft gift vouchers can be redeemed online at lincraft.co.nz or in any New Zealand store and are valid for 36 months from date of purchase.
