Replacement Prescription Sunglass Lenses @ Wal Mart?

[The Don]

I want to get a set of Rx polarized sunglass lenses put into a set of Ray Ban frames that I already own. Quotes have been anywhere in the $200-$250 range, but Wal Mart is quoting a much cheaper price. Has anyone ever used Wal Mart for this sort of service? How was the experience?

I had a pair of regular glasses from wal-mart around 10-12 years ago, no complaints. Not sure if anything has changed with them as my insurance does not cover their service anymore (I work for one of their major competitors). The quotes do seem a bit high since a poly-carb lens shouldn't be more than $50 each and tinting is in the $20 range.

Edit:
Just saw you mentioned polarized. I have no idea how much that adds to the cost so the pricey quotes may be correct.
