I actually did it. I bought a Snuggie!
I called the toll-free number but it was going to be $17.99 +$7.95 s&h + an extra $7.95 s&h for a 2nd Snuggie. Nope. No thanks.
Then, I was walking through Staples and saw 2 boxes left. They were $14.95 each. I purchased 1 because I wasn't sure we would like it and the other box had been opened and I didn't want OPF (other people's funk) on my Snuggie.
It's okay. It does keep you warm, but the collar falls down. If you are sitting on the couch, it works great. But when I sit at the table to homeschool, my back gets cold. I would not pay more than I did for it. Who knows, if I get into sewing this summer, I just might make a modified version for everyone in the family for Christmas.
