Buy at your own risk!!
I am very disappointed from Houseoftoners. I had very good customer service from my first order when one of the cartridges had a problem. This store honored their promise to make an exchange/return for items purchased within one year. HOWEVER, I could not get any customer service in my second order when there was another cartridge problem. I contacted their customer service several times via their website return service, email, and live chat without any response. So far, their cartridges have a 50% fail rate for me!!
