btc-e.com accept Ukash. Register with them and you can deposit the value of a Ukash voucher in your account and buy some btc.
don´t bother with depositing ukash into btc-e... fees are way too high
just looked it up and ukash is neither available for nor for $ deposits... therefore I am not sure where you got the info from
that btc-e accepts ukash.
But as said in my quoted post the fees were a ripoff (like 7 % per deposit) anyways
