“Hello,
My experience with the Easy Keys website has been good overall and easy to use.
One improvement would be adding clearer product details and estimated shipping times before checkout.
Thank you,”

“I was able to navigate the web site ok.
When I checked out I was charged a shipping fee.
When I put my items I the in the cart a pop up said that is I purchased $35.00 worth of product I would receive free shipping. I don't remember seeing a disclaimer that said that the purchased items had to qualify for the free shipping.”
