I started putting the weekly bonuses in my calendar back in May. While I haven’t figured out Ibotta’s algorithm, at least I’m able to spot any patterns. So far, it does seem to be random when your redemption activity stays constant.
At any rate, I got $1/10- my third of the year, after the last one in mid-Sept. I need 20 more for the Snowflake bonus, so I’ll take it.
