Xbox Game pass 7 days?

I want to get the Xbox Game pass Ultimate for windows 10

However, I have seen that if I buy 7 days again and again, that is cheaper. Hence my question, is that possible? Can I redeem keys for 7 days over and over again?

A little hint.

Last week gave an offer where you could buy ultimate for 1 euro 3 months.

But don't know if the offer is still available

Get this

You pay 1 euro for 1 month and get 2 months free.

Are 3 months for 1 euro. Just a very good action.

Apparently still current the offer ^^

This trick should still work normally. This saves even more
