Problem with buying Pixel XL in Google Store!

Hey all,

I'm trying to finance the Pixel XL (Total cost $940 with device protection and tax).
Device protection (+$99),
...but Synchrony Bank only approved me for $900
and won't raise my limit by $40 to cover the tax on the sale!

I wish there was a way to pay the $40 separately but Google Store has only 1 payment option, (unless you have a promo code).

I would remove the device protection but you have to buy it with the phone in order for it to be valid, and with a phone so expensive I can't risk not having protection.

Does anybody know of a loophole or something else I can try? Financing through Verizon is not a preferred option for me because I want to try Project Fi when I'm done with At&T in 2 months.

Thanks so much for your ideas!
