I made an EBAY purchase a few minutes ago and got 8% cashback. Depending on how you search on Bing will determine how high the cash back percentage will be. So try several search terms.
Don’t just look at the stores listed on BING.com —- Do a SEARCH and on the right hand side the gold cashback coin may appear. For example search ATT and you will find 35% cashback is offered. The same is true for T-Mobile.
