Not sure what your guys experience with Bing is but I'm not pleased by their services.
Last year I bought during a 50% off Promotion some very expensive (authentic) watches at thewatchery.com ! First off the Promo ended after just 2 days "due to high demand" without prior notice. The Cashback should have been processed after 8 weeks, however 7 days before that I recieved an email from Bing saying they had a Computer error and it would be newly posted to my account - with another 8 week waiting period !
We are not talking peanuts here, let me assure you that and the money was accounted for.
Bing replied with a standard email referring to thei T&C. Thats it.
Never again for me.
Fatwallet might not be the greatest but I never had many issues !
