Can I buy an Uber eats gift card with an Amazon gift card?

Hi guys,

I got an Amazon gift card. The thing is that I don't live on the USA and international shipping is a mess right now (specially to my country). So right now buy something on Amazon is that a good idea or ideal for me, so I was thinking on buying an Uber gift card.

But I have a doubt if that is possible, buy an Uber gift card with an Amazon gift card. Also, do you know if taxes apply to an uber gift card on Amazon?
