HELP: What vouchers are popular among Taiwanese?

Hi,

I’m a researcher from Singapore. I’m giving out incentives for my Taiwanese participants and will like to have an idea of the type of vouchers that are popular among Taiwanese people.

What vouchers (and from which companies/stores) will you be happy to receive?
Which vouchers come in NT100? So far, I have only found out that 7-11 has NT100 vouchers.

Thanks!

There is also 100 TWD voucher for Family Mart.

SOGO also has 100 NTD vouchers.
