Grab your invite link under the account tab. Just heads up: you won’t see the reward balance update until your friend’s order actually ships, not when they place it. Once it hits, it applies automatically at checkout as store credit. Definitely check the expiration date, though, because they don't last forever.

Zulily is pure flash sales, so things vanish fast. Pro tip: buy one small item on a Friday morning to pay the shipping fee once, which unlocks free shipping through Sunday night. Just double check sizing charts because almost everything is final sale, and expect shipping to take three weeks minimum.

Zulily takes standard debit, credit, and PayPal at checkout, but don't waste time looking for hidden payment methods. Heads up though: items in your cart aren’t reserved until you actually pay. Use PayPal for a faster checkout so your stuff doesn't sell out, and place one small order early to unlock the daily free shipping window.

Zulily’s shipping is annoying since it starts around $6, but there's an easy workaround. Buy your smallest, cheapest item by itself first to pay that base rate. Doing that unlocks free shipping on everything else for the next 24 hours, or through Sunday night if you make that first purchase on a Friday.
