You will have to call in to the store or go in and see. The stock changes daily and one day there could be exactly what you are looking for a 20 minutes later it's gone. It really all just comes down to what is brought in either through pick up donations or drop off. Stackable though are incredibly rare and they have no had any in a few months.
You might be better off going in or calling the store directly. They did have a handful of washers and dryers when I was there last. Their inventory changes quickly. The staff is amazing always helpful and cheery.
