Just noticed on the store that there is a banner for each product.
For example for Mavic pro that I want to buy says "we've got the perfect deal to make your Mavic Pro unstoppable".
Problem is I don't have yet a mavic pro, so I'm not sure what should I expect as a new buyer.
Problem is a little more complicated, as I'll be in US as a tourist from 17th to 25th and don't know if I can order to be shipped at the hotel I'll be staying at.

SO... big question is should I stick to original plan to just get first day a mavic pro/m pro fly more combo and hopefully have enough time to RTFM to fly it on the eclipse day (I'm tabula rasa about flying a drone), or wait until 22th and hope for a better price or more accessories in the standard price?

Thank you and sorry for my non-native english.

I wouldn't count on getting it shipped to a hotel. I could barely get it to my house...DJI has crazy restrictions on shipping.

You could pick one up at a Best Buy.

It's maybe difficult to decide at this moment. I would suggest you to prepare in advance so that your travel will not be affected.

As suggested above, head over to Best Buy and purchase one there while you're here on vacation; kill two birds with one stone.
