If you just order the common eyeglasses, you will get it after two or days from Walmart. The service of Walmart is good which will absolutely make you satisfied. If the eyeglasses you order have some special requirements on the lenses or the materials, you may wait for more than one or two days of special processing.
So, it looks like you have already made the payment and are eager to get what you care for right? However, it will take some time before you get them. And that depends on them, totally on them. But there are some things you can do to quicken the process of waiting. Just make frequent phone calls to hurry them up and see if they have begun to deal with your order. Sometimes their service would be quite lousy, you should do something.
