This deal has ended.
Amazon, in what seems to be an attempt to clear out, now has their private label brand of Pike Street Flannel Sheet Sets (Twin and Full are still available in most sizes) for $5.99 each, despite once being $17. Six colors are available. These are related to Amazon's Pinzon line of private label products. Shipping is free if you spend $25 and there is no sales tax (except KS, ND, WA).
