Lenscrafters (Fredericksburg, VA) will tell you that single vision lenses that they don't have in stock will be delivered to them in "a couple of days". For single vision lenses for my 20 year old son, I actually believed them because it was such a simple, no frills order.
Don't be fooled into believing them. I called back after a week and they still have not received the lenses in the store. Whilst the delivery time is out of their control, the fact that they lie about the estimated time to the customer is in their control. Clearly they lie, assuming that you know no better.
I had not used Lenscrafters for several years & should have stayed away. I hate being lied to when they've already got my money.
