The new iPad will be available at Best Buy, Radio Shack, Sam's Club, Target, and Walmart. The lines will likely be shorter than the Apple Stores, but these stores will have a smaller inventory.

Here's a quick overview of each retail store selling the new iPad:

Best Buy: The stores I spoke with said they'd be selling the iPad on a first-come, first-serve basis during regular store hours. Many stores open at 10 a.m., but some open earlier. This could be a good option if you need extra beauty sleep.

Radio Shack: Not all the stores I spoke with will have iPads in stock on launch day. Instead, these stores will take orders on a first-come, first-serve basis when the store opens, and then ship from a warehouse to your home for free within three to five days. This is a good choice if you don't need an iPad this weekend, but you also don't want to wait two to three weeks. Radio Shack also accepts old iPads as trade-ins, though you might want to check first.

Sam's Club: One store said it wasn't sure when the new iPad would be coming in. Another said it was only expecting 64 GB models, and that the store opens early for Business and Plus members, which means regular members may miss the first crack at a limited supply. This doesn't seem like a great option for waiting in line.
