Get this Marc by Marc Jacobs Diamond Lurex Scarf for 70% off at Piperlime! It is currently on clearance for $46.97 instead of the usual $158.00 and shipping is free! Because this is a clearance item there are no returns, but you don't generally have to worry about sizing on a scarf so I'm going for it!
One of the awesome things about Piperlime (aside from their great sales) is that when you order through them, you get free 3-5 day shipping on your purchases at their site AND at their sister sites, Old Navy, Gap, Banana Republic, and Athleta! You can shop all of those sites and add items to a communal bag and as long as there is at least one item in your bag from Piperlime, the whole order ships for free! So while you are picking up your scarf check the sales on the sister sites to maximize your savings!
UPDATE: Take an additional 20% off of sale prices until 8/5 with promo code EXTRA20! That makes this scarf only $37.58 before tax which is a total savings of 76%!
