I believe they do have a delivery system, but I would check the website to make sure it is still running. Especially with the way the shelves have been lately
Giant delivers via Peapod, though I don't believe orders are picked from the Horsham store. Mine have been picked and delivered from the Willow Grove store (doesn't matter to me). Great service, but unfortunately, as I write thi on 03/19/2020, they don't seem to have any available delivery slots for the next week +. Target uses Shipt Shoppers to shop for you, and still seems to have same and next day delivery available. A bit more costly, but if you need/want it, it's an option.
Yes
Not certain about the Horsham location. I know they offer the Pea Pod service. I would call
