not sure if you guys have seen this, but:
$30 off a $100 purchase at Estee Lauder
if i'm not in a low buy, i'd totally be all over this. i've loved all the estee products i've tried, and i think the brand is underrated. i especially love the lighter version of their foundation, and their concealer is my HG!
edit: btw, if you're a new gilt customer, you can always use WELCOME20 to get 20% off on top of the discount!
