The Goodwill nearest me puts out some of the clothing items in the morning and sells them for 1.49 per pound. Much cheaper than 4.79 per shirt. I've found some aweful looking plaid shirts and shorts in there that will look awesome in a quilt.
I've been on a mens-XXXL-plaid-or-stripe-cotton-shirt hunting expedition since Bonnie Hunter was in town a couple months ago. :D
