Rather than trying to search in another LensCrafters store, I decided to give the local Site for Sore Eyes a chance, given that they'd been so nice to Cheryl. (The last time Cheryl was in California, her glasses needed repairing, and we stopped by the Site for Sore Eyes store at the Hub in Fremont. They repaired her glasses at no charge, even though she hadn't bought them there.)
I was pleased when not only was the first pair they showed me just the sort of thing I was looking for, but they offered to match the 30% discount that LensCrafters was offering. So I probably ended up spending about the same as I would have done, got glasses I like better than I would probably have settled for elsewhere, and gave my business to people who had been nice to us. And I was able to charge the cost to my prepaid healthcare FSA card, so I'm not even out of pocket any money. A nice deal all around, that was.
