Now I am clear...
Let me think about it...
I need only 1 email id,
so if I divide £10 with 250 emails then the price for 1 email id is £0.04 equivalent $0.05 equivalent BTC0.00007122.
So are you interested to sale 1 email id?
I know you are offering bulk quantity. But at this moment I don't need that much.
If your looking for a single email I'd suggest a free provider. This is for bulk only not individual emails.
I was offering your 25 for free as a vouch, but hey-ho.
