Wonderful analysis. I hope you're not counting the commute it takes you to get there and I'm sure you're using spare time to go. I have a cousin who lives near a Dollar Tree store and whenever I visit him I stop buy that store and buy Colgate liquid toothpaste, Sensodyne toothpaste, acetaminophen, Neosporin, scotch tape for boxes, and also other items that at a store might go for 1 dollar while on sale but not always (tuna can, detergent, liquid soap, 1 pound French fries, mayonnaise, etc.)
