You got some great bargains!
My friend and I went to one where the guild members putting on the show had a couple of big boxes full of all shapes and sizes of fabric scraps. We got to fill a gallon size ziploc bag as full as we could get it for $2. Then they had other bags with various fabric remnants for 25 and 50 cents. I got one with several really nice pieces of velvet, some larger than FQ size for 50 cents!
