Incorrect Item Amount Format

[ypinskiy]

I am attempting to add a negative price product as a discount. Using the addToCart on var DiscountProd = { "business": "test@email.com", "item_name": "January Discount", "amount": -10.00, "currency_code": "USD" }; makes it show up correctly in the cart. However, checking out gives me a Paypal error page where it tells me that the item amount is incorrectly formatted. Attached are images of the cart and the error page.

This is not specific to the minicart -- PayPal does not allow for negative item amounts. If you want to pass a discount please pass the discount_amount value per the PayPal Buy Now button spec. See https://github.com/jeffharrell/minicart/blob/master/test/unit/product.js#L102 for an example
