ok so I plan on getting the Series 4. I have a series 0. I want to get the series 4 on finance. The nearest apple store to me is an hour away so in order to trade in my current watch I would have to do it online and then receive the gift card. I have just been speaking to an apple advisor and they informed me that I can use the gift card against the purchase of the new watch (the gift card amount being taken off the total of the new watch and then finance is calculated after). Now this got me thinking, can you use more than 1 gift card to take off the total, thus making the monthly payments even lower? Can anyone shed some light onto this?
