If I have ever bought bias tape, it was probably 30 years sago...
Too stiff, too narrow, too limited. I use scraps too, and have a long boring tape making session whenever mojo deserts me. I keep it all rolled on bits of card, and stuffed into a ziplock bag. I don't use bias makers as I find they limit the way I may want to use the tape. I tend to cut 2" or 2.5" wide, and trim after applying if I need narrower. I often fold it double, then fold the fold over the raw edges iyswim.
If I do want it folded, I use a couple of needles in the ironing board cover...
