Found these are decent price for 2 shirts
Shirt 1: Red, White and Navy
Shirt 2: Navy
Great for layering or wearing alone, this pack of two shirts features a straight hem, short sleeves, and a tag-free crewneck for everyday comfort
Everyday made better: we listen to customer feedback and fine-tune every detail to ensure quality, fit, and comfort
Note there is so many option and formats that you can look through. This seems to be the cheapest, but many options for under $10 for 2 in different styles
