Ah... I just now figured out the check amount. I subscribed when they began as an annual subscriber at $110 a year (which equates to $9.16 per month).. better than the $12.95 they were recently charging....so it looks like the $18.32 is for 2 months worth of bags, however my calculation was that I was due 3 bags (because of the interruption when the stopped service last summer). Oh well... at least it done and over and I received something back.
