The answer is to not use broad match use broad match modifier and other match types or you will always run into these problems.

The other way to do it is use broad and phrase match negatives instead of exact match.

Without seeing the account this is the best i can do to help you

No problem - if you use modifiers and phrase and broad negatives it should solve your issues- If you need more info on modifiers pm me

If you see alot of impr for the keyword "buy keyword" after you run it on phrase etc i would make a new agroup for buy with the buy keywords with ads focused on that intent. This will allow you to bid on them separately and talk to what they are looking for better then a broad or phrase.
