Aren't credit card rewards a bit too complicated? (would love help figuring this out :) )

If anyone is super into credit card rewards or has a friend who is or has given up on credit card rewards entirely for cashback cards bc rewards are too complicated, my startup Taekus is doing some user testing on our prototype designs and we'd love to get some more people on the calendar to make sure we're on the right track!In exchange, we can offer 1) an absurd photoshop of something 2) a personalized limerick written by yours truly or 3) an email consultation abt how to maximize credit card rewards for a particular trip you have in mind for after covid... whenever that is.Anyway, here's the signup, if anyone has a spare 30 min next week. :)https://calendly.com/kat-lin/ux-testing-taekus?month=2020-07
