Come over the river to NJ. WE have some strange laws over here too. Some grocery stores sell alcohol, but a chain can only have 3 stores that sell alcohol in the entire State (but ShopRite is a coop and it's store are independently owned, so there are more than 3 ShopRites that sell alcohol)
In Begren County NJ it is illegal to sell clothing, lumber, electronics, and assorted other items on a Sunday - but you can buy alcohol after noon. That's right, on a Sunday, entire shopping malls are closed, but liquor stores are open after lunch.
When we were staying in AKL, my brother took a bus over to Disney Springs (DTD at the time) and bought two 12 packs of beer from the Speedway (Hess at the time). He then rode the bus back to AKL with them. He had people offering to buy them off of him.
We usually place an order with garden grocer when we go. We also order food because we are in a DVC unit with a kitchen, but we throw some beer and wine on the order as well. They do make water (liquid) proof bags meant to pack things like alcohol in. It does not so much protect from breakage, but contains the liquid if it does break. I had a bottle of rum break in my bag once on the way back from the Caymans. That bag smelled really good for quite a while.
