Can't believe this mob hasn't been mentioned on here for a while, but basically Leaptel are offering $10 off for 12 months on their 50/20 and 100/20 plans with $20 a month for 12 months off their 250/25 plan.
50/20 - $59.95 100gb or $64.95 for unlimited for the first 12 reverting to $69.95/$74.95 after
100/20 - $79.95 for the first 12 and reverting to $89.95 a month after, you can bump it up to 100/40 for an extra $10
250/25 - $99 for the first 12 and reverting to $119 after.
CGNAT is enabled by default however you can turn it off in the my account portal (please don't unless it absolutely must be) or you can buy a static for $10 extra.
Local Aussie support based on Melbourne.
Pro: longer 12 month discount
Con: more expensive for new customer discount
Worth it? No. (although 250/25 seems to be better value than others)
