Pickup small items and deliver home

Need to pick up two small items from a grocery store. They're just 2 bracelets made from this cloth type material. I could buy them over the phone and all they need to do is go inside and pick them up. I need them delivered to my cousin by today evening. The store is only about 10 minutes from my cousin's place. I can give the address of the store and cousin's house once someone can do it. It's around the overland park area.
