Get your taxes done using TurboTax

What about mileage? If your Amazon (or other product testing items) are shipped to a business "post office box" street address instead of your home address (for security and convenience), can you deduct the mileage when you go pick up the packages/items?

 

If you are keeping track of the items purchased and the amount rebated, do you need to keep track of what is done with each item?
