I'm probably the last person that knows about this but... I bought tranquility diapers online today and found out an option exist where I can have them shipped to a fedex location near my home and held there until I can pick them up. This is known as location hold. I called the company (northshorecare) and asked if I can have the package shipped to fedex and held there until I can pick them up. Easy as that. I remember reading articles about how people don't want them shipped to there home due to the possibility of others finding out.
Everyone may or may not know about this... though, I thought I would share.
I live with my brother and he's pretty good about privacy... although, he's a Dr. (rheumatologist) and he might know the label or the company might send pamphlets or adds and what not. I'm trying to not use his address.
