Ladies!! Where to get toiletries? (Shanghai)

Hi everyone! This question is mainly for the ladies (although if any males have helpful advice, that would be great too). I'm relocating to Shanghai from USA in April for 3 years. As I continue my research, it seems that tampons and deoderant/antiperspirant are not sold in China. I could be wrong, but are there any stores or online stores that sell such items? I've even tried Amazon.cn and anything I type in the search box doesn't work. They just show me books!!! I think I found tampons on the site, but it would obviously be more convenient to just go to a store. Thanks in advance :)
