Did you know Countdown glass containers eStamps are transferable? This is a good way to consolidate stamps for households with multiple Onecards.
You can do it here
https://shop.countdown.co.nz/shop/content/glass-containers
Remember the last day for redeeming the stamps is 21 Feb.
P/S:
If you have a few stamps which would otherwise go to waste please gift them to me (card number 9480040143478). I just never have enough glass containers! Thanks
Update: Thanks to cheapies' super generosity I have collected more than enough containers so no longer need stamps. A few people are still collecting though, see the comments. Thanks.
Also the eStamps are linked to specific cards so if you have multiple cards linked to one onecard account (e.g. husband and wife) then you'll need to transfer the estamps to one card otherwise you'll have estamps scattered across multiple cards.
I see countdown have some stocks again too - I cashed in my 90 estamps today.
