I believe most of the MagicBands being sold everywhere by Disney are now MagicBand+. One important thing to note is there are tiers to the costing, with basic, solid-color bands being cheapest at $35 and limited editions running up to $65, but they all do the same thing.
Keep in mind, if you have a WDW hotel reservation, you can pre-order MagicBands prior to arrival at a discount. For example, the plain MagicBand+ that sell for $35 on
ShopDisney are only $25 if you pre-order them with a hotel reservation. You can also still get MagicBand 2.0's through hotel reservations (the ones you used to get for free). and those are only $9.99 each. Those are only available with a hotel stay and aren't sold elsewhere that I can tell. The range of choices when purchasing through pre-order is huge too (like 2 or 3 times as many options as you'll see in DTD).
Also, if you're travelling to WDW, you can continue to use those older MagicBand 2.0's as well, you just don't get the added features (haptics, LED's, game interactivity).
