Night nappies

Can anyone recommend a really good cheapish night nappy - 12 hours no leaks?

I currently use Huggies Nappy Pants for my 2 and a bit year old as he is a fidget bum and they stay on well and never leak BUT are $30 a pack of 25 at Woolies here ouchhhhhh!!

For Soph ( 6 months) I use Air but again these are $28 a packet here for 40 something

They are both awesome and never leak and are both on for 12 hours just a bit expensive.

Surely there must be cheaper good ones out there? I have looked on Baby online but their postage is $8 so would prefer to buy whats at the supermaket in town?

Any suggestions?

Thanks ladies

What about pull ups on Ben (i'm not sure how absorbant they are thou). But a little cheaper that the nappy pants.

have you tried homebrand?     
i use cloth nappies but when we go and stay at my parents place i use sposies and always get homebrand or budget naps.....these last charli 13hrs overnight without problems

if you wanted to buy bulk, i found sealer and cien nappies are on par with air nappies

I use (but not for much longer as shes now dry) Home Brand on Keira and Maddi and surprisingly I have never had a leaky night with them. They are usually extremely full but still all in one piece. They often do both of them 14 hours and Keira used to drink her water all night too so they would fill them really well.
It doesn't really solve the problem of wiggly Ben but at less than 30c a nappy I cant complain.
Another fairly cheap option is the Select nappies, they are just as good!
