Can a person go shopping for me?

There are services to bring groceries to your door. perhaps http://www.schwans.com

Need someone to run to the beer store for me.

Ask a neighbor.

You can order online at Shoprite. They shop and deliver.

You can get online services to help you, but if you do not trust them or are a little skeptical then you can ask a person who you truly trust to help you. Also, you can ask in employer or employee to assist you with getting your groceries. Some will help you immediately and others you might have to call them ahead time and give them a specific time to pick it up.

I will shop for you, what state are you in?

Some places will deliver, alcohol may be a little different depending upon which state you're in. Usually, if you kick in a few bucks OR are willing to share the beer, then your neighbor may help you out.

Or you could ask LissaC.

If you are elderly or disabled, there may be a social service agency in your area that can help you with shopping, cooking, cleaning, etc. Or you could help through a church.
