Did you know Countdown glass containers eStamps are transferable? This is a good way to consolidate stamps for households with multiple Onecards.

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.

Thanks to my generous donors Quirkies1 (18 stamps), ohohcoco (2), anonymous (1), another anonymous (2), frugalgal (a zillion) and Wakrak (1) I have got 5 more containers, to add to my existing collection which is crazy number mostly bought from Briscoes and The Market. I thought I'd never have enough glass containers, but now I do. Rest assured they will be used regularly. Thank you all again.
