This can’t be for a single skein? Or it’s definitely priced wrong.
The MSRP is only 5.89, not ever 9.99.
Most stores sell it at regular price under $5.
Everything I can find says a single.
The Amazon ASIN is B0075HFFUG
Seems pricey if it’s for a single skein. Especially because you have no choice in color and no guarantee that it would be from the same dye clot if you ordered enough for a project you have in mind. I would skip this “deal”. Acrylic yarn is not 9.99 anywhere.
