I'm looking for websites that combine shipping..........like diapers.com/yoyo.com/wag.com/soap.com.........are there any others like this, where multiples sites ship for one fee?

My highschool BFF and her daughter have birthdays one day apart, so I try to pick places where I can get them both a gift........but I'm getting tired of using Amazon.

do PB/PBK? Are there any other sites I'm missing that have adult and kid gift possibilities.


thanks for any help!!
