Store vs. Homemade

I love Costco. Living in a small town, Costco allows me to buy quality stuff. And of course, I always end up buying more than I need. But I digress. I bought wonderful merino/silk boot socks. 3 pairs for about $15. Why would I ever want to knit my own socks. So I decided to follow along the Skacel knit along. I am trying a new cable pattern. It means I am going to have to do gusset stitches. I have to measure hor far before the heel. All the reasons why I love Cat Bhordi. So I start a new challenge and listen to the wise cracks about how I can buy socks at a store.
