Not a thing I think is offered here, but $5 seems reasonable for that.
I'm a bad person to send grocery shopping, especially if hungry, because I'll come back with far more than $5 of extra stuff that looked good. We use it eventually, but my wife is better at not buying snacks than I am. Or, at least, at finding insanely cheap bulk snacks.
Going to multiple stores to find best prices... eh. If you're driving, that's probably false savings anyway.
But our 3 year old loves going shopping and is very well behaved about it, so I don't mind it that much.
