Sheinside offers its Sheinside Women's Long Sleeve V Neck Bodycon Dress in Wine Red for $9.99 with free shipping. (Be sure to uncheck the shipping insurance box; otherwise, it adds 99 cents.) That's $5 off list price and the lowest total price we could find. It's available in sizes S to L.
Note: It ships from mainland China and should arrive in three to four weeks.
