Can I just say I need to go grocery shopping, order groceries and get my nails done instead?

You could eat your nails but it would not be a balanced meal. Screw that, food!

If your local supermarket don’t close early, go get your nails done and then go food shopping 😊

Go get you time!

I'm comfused by the question. Are you asking if you should go to the store or place an order? You want to get your nails done too though?

If that's the case, I say place the order for pickup, schedule it for a time when you'll be done with your nails then just go pick it up when you're finished and head home. This would require the least amount of effort of your part.
