I took the glasses that I purchased yesterday, back. They were not comfortable and a bit heavy. I got my almost $20 back. i went to family dollar store to buy a birthday card and some batteries and found glasses there for $5. I think that is where I got my glasses, the last time.
So I picked up a pair of reading glasses to have the next time I have a problem with my glasses. I have several glass cases, so I am going to leave them in the glove box of the car. That way when I leave mine home, I will still have a pair in the car.
So, for less than $10, I left the store with a new pair of glasses, 8 batteries and a birthday card. Good savings!
