Excuses to leave home alone.

While I can drive and use public transport, I never have a reason to do it. There is almost always someone at home which can drive me to where I need, which is often somewhere I need to shop or university, this is very practical and I have no reason to suddenly stop accepting lifts, but I want to get something so I need to be away around 2 hours with no excuse to which I am leaving or why I would go alone.

Im trying to get depilatory cream, but it's not a very common item in my country, I can for sure go get it, but why would I? How can I keep this hidden?

The other factor is that when I am out alone (Somebody else got me there and left), my mom needs to know what Im doing, not in a real time location way, but telling her what I will do and how much time it would take. If in that time she has no updates, she will get worried and later mad.

Do you guys have any ideas on how to get this and other secret products if I cant get them shipped at home?
