I purchased a major appliance with joinhoney.com with Home Depot. I never received credit for it. I contacted Joinhoney and they never got me the points. My transaction on Joinhoney said "Ineligible." I had the same thing with Apple purchased with honey. On the contrary, when I do the exact same purchases on American Airlines Shopping, I get points from both Apple and Home Depot for the exact same types of purchases. Honey is either incompetent or a total scam and they are keeping the money.
Avoid them like the plague. FYI, it looks like they were purchased by Paypal. I hope you like offshore customer service. ;)
