While vouchers last, head over to Gilt where they are offering a $40 Aerie purchase voucher for only $25 (limit 4 vouchers per customer). You’ll get a confirmation email just after you order, and then a second email with the voucher code. It usually takes around 30 min to get the 2nd email.
Note that this voucher is valid at Aerie and must be redeemed by 5/27. The voucher may not be combined with any other offer, promotion, coupon, discount or certificate and must be redeemed in a single visit.
Plus, now through May 5th, they’re offering Buy One, Get One FREE Bikini Bottoms & Tops – no promo code needed as discount is automatically applied at checkout. 
To top it off, shipping is FREE with any swim purchase!
