ASOS just marked down a bunch of items for their July 4th sale, so make sure to check your Saved Items to see if anything you've been oogling is included! I was hoping that they'd release a special promo code for the holiday, but no sign of one yet :P However, I DID find a 10% off + Free Shipping code (CHECKOUTTREAT) on RetailMeNot. To see coupon codes for other countries, go here. Shameless plug - if you are interested in ordering, be sure to take a gander at my How to Get the Best Deal at ASOS post before you hit Confirm :)
For me, a bunch of items just got marked down (yesss!) so I think I'm going to go ahead and order my stuff with the code above.
Last thing, if you're feeling lucky, please enter my mini giveaway, which closes on June 30.
(an oxymoron if I ever saw one ^_~)
