I suggest to Google they even award a small percentage bonus (e.g. 5%) for doing so. For the publisher who focuses mainly on adsense, it could help open them up to adwords. Also, there are quite a few advertisers who set fairly low budget limits on their adwords campaigns, so why not induce them to spend more by pumping their adsense earnings right back into google's hands.
Also, by issuing a check, the money could end up anywhere. Companies as well as individuals often spend frivolously, so why not trap the funds inside of googleplex instead? Makes sense to me.
If they had this feature, how many of you would use it instead of receiving a check?
Google representatives have mentioned that they are woring on this, but no ETA has been given yet.
Getvisibleuk, a large number of people use both Adwords and Adsense. For those, transferring the money back and forth can amount to several % loss in bank fees. Avoiding that overhead will put more food on *their* table.
Google is very old-fashioned with the only-by-check payment, I receive other commission by Electronic transfer, but they do not have it available, I woukd like the credit to use it on my AdWords account but they do not have it available.
