Howdy! Here's how you rock away with Unicorns and Donuts:
Step 0 - Download and install the app. Thankfully, your phone will do that on its own so you don't actually contribute anything to this step.
Enter your DSD account details (if you have em) and your location in the settings. If you don't have a DSD account, you still get free scans! Wow...the developer must be a really really nice guy to not monetize this like other evil apps out there :o!
Step 1 - Go to a local store...this could be intentional, or you may just happen to find yourself in the store with no prior knowledge of how you got there. Blame ghosts or aliens in such an instance.
Step 2 - Congratulations! You're at the store! Now whip out your phone, and as you walk past different items, scan them with this app. That's basically like taking a picture of the product, BUT - you don't have to click! So it's even easier than taking a picture! And even better, you don't need to say 'cheese', 'geese', 'please', 'sneeze', 'freeze', or any other random eezarhymic words. (Yes, I just made up the word eezarhymic, it means words that rhyme with 'eeze', you are welcome webster-mirriam).
Step 3 - The App tells your glorious face if the product will be profitable. If yes, just grab the product and send it over to FBA (see DSD Genesis tutorial for this). Easy Money.
Step 4 - ADVANCED STUFF!!! Not really, it's pretty easy. If the app shows something profitable with a donut next to it -- grab a few of those --- it means they sell fast. Grab a baker's dozen of them (see the donut connection?).
If the app shows a Unicorn head next to it, then this is the stuff of dreams! Get the product for FBA, but also go to Genesis traditional training and see if you can't source it yourself to establish a beautiful monopoly yourself! :)
Step 5 -- Thank the developer of this app. He's a really nice guy who works with a really nice team of coders.
Important Note: Unicorns are NOT nice creatures as opposed to the image they present thanks to the out of control Unicorn PR department.
