gift card not compatible with the entry offer 3 months 0,99 then 99 sek

[1öre]

I would like to give one year premium contrat to my wife as present.

Under the section "Gift Cards" 12 months cost 1188,00 swedish kr (99 kr/month).

Under the section "upgrade to premium" (from a free account that has never be premium, like my wife has) there is an offer of 9 kr for 3 months, then 99 (12 months will be: 9x3 + 99x9 = 918 kr).

I can open her account and pay with my card from there but the Gift Card looks more romantic.

I wonder if there is a possibility to use the offer and give it to her as/with a gift card.
