Adrianna Papell ships for free as long as you choose economy ground shipping, which takes 7-9 business days. For standard 3-6 day shipping they charge $9.95. However, standard shipping becomes free if your order is over $149.
The free shipping only applies under certain conditions. On domestic orders, those within USA, you have to spend $50 on your purchase and Lulu's will give you free shipping. However, if you are placing an order internationally, you must spend $150 to qualify for free shipping.
