Now,you can add only 1 coupon in one account .
Correct. And you cannot use the check/bank method to redeem a code either. So as of right now the only way to use coupons is to use a VCC + highest voucher amount possible (which is $155 at the moment) per 1 account.
It's very much a pain in the ass and makes it almost worthless (which is what bing intended I'm sure as the codes were supposed to be for only new customers and max 1 coupon anyways).
The ONLY good news out of all this is that for legit account owners (I run legit campaigns that I pay for, I always have, even before I started to use bing "packs" myself) is the the avg CPC
should lower without all the people using "packs" which would jack up the CPC big time.
Those who are saying bing will allow packs again here soon are purely
speculating. Allowing people to continue gaming Bing Ads = tons of lost revenue for bing so it would make absolutely NO SENSE to allow them again.
Those who are saying they will because the ad spend will be down severely also are talking out of their ass. Just because their ad spend
appears to be down does mean they are losing tons of money. I bet the majority of that daily "ad spend" was people using "packs" which means people were not REALLY paying for those ads.
Bing ads packs are OVER! Time to find a new method I'm afraid.
