Great Prices and Great Experience
"I’ve purchased two TVs through Greentoe, and both experiences have been excellent. Best prices I could find anywhere, and both TVs were delivered right to my door without any issues.
My only mistake was forgetting that Greentoe offers a lot more than just TVs! I recently purchased applioances elsewhere and afterward realized I should have checked Greentoe first.
Greentoe will definitely be one of the first places I check before making a major purchase. Let's get the word out, and let the free market dictate prices. Craig Barton Scottsdale AZ"View article
