For the past year Bing has peeked my interest because it's still a gold mine if you know how to monetize it but as with everything to find the golden nugget you often need to (split) test different things which can cost quite some money.
So I always trying to find ways to "cheat" the system and in this case, trying to find working coupons.
The first time I looked for it last year was on an other forum and found a seller but it was nothing less than drama. First the coupon didn't work, no replies, had to do a PP claim and after 2 weeks finally got a working coupon but burned through that really fast as monetizing is not as easy as it seems. After that got sidetracked with other things but still wanted to give it a go because I know people are banking quite good on it so I could surely too.
This time I searched BHW for coupon sellers, not too many but arrived at this thread, added martworld11 to skype and yes be aware there is a fake dude so if you don't trust it let him send you a PM on BHW after a skype conversation before you pay, and ordered a coupon to test.
Received the coupon quite fast after payment.
Created a new bing ads account, entered the coupon and BANG, free $100.
Now I read in this thread there is a possibility to add a second coupon on top of the first one. TBH I was quite skeptical about that but it seems like Bing does these promo's every now and then so I also bought one of these to see if they work.
There is a catch on the second coupon though, you first need to spend $25 before it get's activated. I had a small miscommunication as I thought it meant it will get activated once you uploaded $25 but it has to get spend first before the second coupon works.
Nevertheless, like the first coupon, the second coupon is redeemed as seen in the screenshot.
All with all, nice seller, good communication and great products, will definitely do business again in the future.
On a side-note, you never know what Bing will do in the future so I would definitely buy the second coupon also while it lasts
