I use Telstra prepaid and usually recharge $30 per month. I used to leave it on auto recharge to get 30/31 days per recharge, but this month I checked on ebay and found that you can buy prepaid recharge vouchers for 20% off the face value.
Purchased one and it worked fine, so I paid $24 for my $30 recharge. I realise this recharge only lasts 28 days, but it's still a bit of a saving.
OzBargain guidelines don't allow this to be posted as a deal, so here it is. The seller was ausvouchers. They told me the vouchers are usually delivered within 12 hours, and are within one hour if they are online. Mine was delivered in 5 minutes - probably because I purchased right after they responded to my questions on ebay.
Not afilliated, just felt this discount was worth sharing. Expiry date on the voucher was two years.
Is $24 a month for 3GB worth it though, if you don't necessarily. need Telstra coverage? Also my $30 Telstra recharge runs out in 60 minutes, so no time to think about it, I'll give it a go.
