Is It Possible To Use Multiple Promotional Codes for Google AdWords?

[DR70095]

I am managing two separate Google AdWords accounts and with one I was able to add 3 different promotional codes so I got $300 of Google AdWords for free.

I signed up for Google AdWords for another business with a separate login e-mail address. I used the code that I was able to generate and a few days later I recieved an additional code in the mail. I tried to use this code and it said I was only able to use one promotional code per account.

Does anyone know why Google has this inconsistency? Was I just lucky the first time or is it possible to use multiple vouchers?

Thanks

It also says what type of account they are good for. If the account was activated recently, you might not be able to use more than one. Since you have an account that is older and has spent more money, it might be qualified for more discounts.

I think it depends on the source. We typically get a code from Google every 6 months or so, and every now and then I come across different codes from various other services. No problems using them, however if I try and stack codes from the same source / type to the same account they don't work.
