But the savings and your timing may not workout. The drive to Toledo may not workout so well either unless you are going there or they are coming here for another purpose.
You can also buy it at the pet store or buy it online (Amazon, Pet Solutions, etc.) and they will ship it to your address. You don't have to drive and it works 24/7.
Really this one is easy to solve.
