Hey guys, I'm hoping some of you who use AdWords a lot could let me know how to take advantage of coupons. I have received 3 AdWords coupons in the mail (from Google) and was able to activate them all within one account. Can I run unlimited coupons in my AdWords account? Or will it stop activating them when I register 5,6,7,10,22? I would love to run my AdWords account on buying $50 coupons for $3 (as an example). Is there anything I need to be aware of though? Does AdWords have limits on coupons?
