I had lasik about 5 yrs ago, and hoped I'd be done with glasses even though the surgeon warned me I'd need readers. Well, today I went in the "Dollar General" store to buy 3 pairs of readers to leave scattered about the house and shop and as I was paying the clerk whispered "since my manager isn't here I'll tell you they ain't but a dollar a pair down the street at the "Dollar Tree". Basically, she took my money for three pairs of glasses and I could have had twenty pairs.
