Amazon takes up to 70% off a selection of babies' and girls' dresses, with prices starting at $4.57. Plus, Amazon Prime members bag free shipping on all orders. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping starts around $5.) That's the best sale we've seen on these items from Amazon.

A best bet is the So La Vita Toddler Girls' Print Dress in Navy, Red, or Blue (pictured) for $4.57 with free shipping. (Non-members can spend $25 or more to qualify for free shipping; otherwise, shipping costs $4.98.) That's the lowest total price we could find by $10. It's available in sizes 2T, 3T, and 4T.

Amazon Prime membership is $79 per year; however, Prime is free for college students for six months, and free for parents and caregivers for three months.
