Marc, I am in the same boat as you, too expensive and timely to cash a cheque.

Like Lee says, merge all your ccbill accounts into one and then get them to wire you funds at a higher payout point, like $500 or $1K. Also, ccbill can merge your affiliate accounts into your webmaster account if you have one with them, which also makes life a lot easier.

Do you have an epassporte account? Most sponsors will offer that as a payment option, even if its not listed just get in touch with them. If a sponsor does not offer an epass payment, tell them they should! If enough webmasters complain and stop sending traffic they will change their mind.

Finally, if you love a sponsor and they don't offer epass, they will likely offer wire transfers - just get them to set a higher payout point, you will get less transfers which means less wire fees.

cheers,
Luke
