I have ordered from QVC many, many times and have always been thrilled with my purchase. I have never once returned anything. I love the fast you can buy and pay over time and they ship things really fast.
My complaint is lately they seem to have ZERO selection and inventory. I have shopped for a computer or laptop on a few occasions and there were hundreds of options. I have shopped for speakers, there were tons of options, I bought a ninja blender a long time ago, and was looking to buy another one or possibly some other small stuff for the kitchen, and the selection is horrible. No Ninja blenders at all... Also, used to be so much stuff you could pay for 4-5 or even 6 payments. Now, almost everything is only 3 payments.
I will likely still shop here, I love the site but I won't be buying much until they get a better selection and offer more payment options.
