Where can I buy cheap/reasonable clearblue fertility test sticks?

Hi,

I have some left over from last time but the expired in Oct 2012. Can I still use them?

I can only find them online for around £1 per stick (10 for £9.95 etc) which seems very expensive to me? (money is tighter this time around!)

Does anyone know anywhere in the UK I can get them any cheaper? Ive looked on ebay but they dont seem any cheaper.

Thanks

yes I used expired ones last time and had a clear positive on them

I buy my other sticks from Amazon

bumping for more responses

also some people use cheapies as a kind of backup and save the spendy sticks for confirmation

Thanks atomic!
