A:AnswerI felt the same way. The only way is to be vigilant and keep tabs on it whenever possible. I saw it go back down to $30 early in the morning when I bought it. I only bought 1. If I didn't get it when it was on sale, then so be it.
I say keep an eye on it next week before Christmas as stores want to make a last minute push. This is assuming that Best Buy will drop it back to $30.
A:AnswerNot sure. App is easy to download and user friendly, even on a phone screen (although can use a tablet too). You have to "connect" (pair) the device with BB-8 each time you use it, so you may be tethered to a certain area if you can use it on a computer.
A:AnswerNo. Once cartridge PKG is opened, it cannot be returned/ exchanged. Unfortunately, honest customers are punished for dishonest ones. I bought 2 pack, one cartridge defective, so I was out the expense.
