To determine the cheapest option for 6 shirts, we can calculate the price per shirt for stores 1, 2, 3 and 5.
Store 1: $7 each
Store 2: $14.99 for 2, so each shirt costs $7.49
Store 3: $20.95 for 3, so each shirt costs $6.98

Although Store 5 offers a deal, it isn't possible to buy exactly 6 shirts. Therefore, Store 4 with a price of $41.95 for 6 T-shirts is the cheapest option.
