I purchased a pair of contact lenses. Immediately after putting one on, I noticed that it felt hard and uncomfortable. I let the vendor know that the packaging of the contact lens was different and had an older expiration date. The second day I wore it, it broke. At the request of 1-Save-on-lens staff I mailed the lens back to them. Their staff determined that it was not defective, how? I have no idea. I did not get a replacement or a refund. Several phone calls and emails serve to confirm that if it sounds too good to be true, it is! Stay away!
