I have a bunch of Singapore Airline miles expiring (not much, about 7k) and don't have any flight redemption opportunities coming up.

Thinking of converting them to Krispay. But I don't live in Singapore. But will be transiting in Changi Airport later this month.

Do any of the shops at the airport accept Krispay? Or is it just shops in Singapore proper itself?

Debating whether to convert the miles to Krispay, or use them for KrisShop (duty free to collect at the airport / delivered to my seat).
