heapsort: Given there has been some mention of budget tools (well, just YNAB) I hope it's not too off-topic to ask if anyone here uses (or has used) heaps! which is a free online tool from KiwiBank.
Funny story about that. About 2 years after I divorced my first wife, I signed up for heaps!. The sign up process was unfriendly (in that, that right after sign up the account was not functional and there was no clear message indicating that I should wait. I wrote to support, did not get a reply. In 24 hours time I was able to log on successfully. In about 8 days (!) I received a pre-canned message about apologizing for inconvenience and telling that an engineer is looking at it. In another 3 days, it was followed up by an email saying that the problem is now resolved. But I digress.).
So I signed up to heaps! and I looked at the statement (transaction) area. To my great surprise I saw a recent statement form my ex-wife credit card, along with a statement from my own. I phoned her and asked "did you recently spent 25.18$ in Gilmours on your kiwibank credit card?" And she was like, "How do you know?"
I closed my heaps! account the same day and never looked back.
