I had a similar situation trying to get contacts. I let them talk me into getting two boxes of single vision contacts and reading glasses because the optometrist told me nobody makes bifocal contacts in my prescription (and they were a weird brand of contacts that nobody else has even heard of, so good luck buying them anywhere else). After a few days of struggling, I stopped in at Lenscrafters and found out both Bausch & Lomb and Acuvue make bifocal lenses in my prescription. This place wouldn't take the unopened boxes of useless lenses back even for just a store credit.
