I very rarely use checks now. The landscaper is all I can think of at the moment. Everything else is credit card, or occasionally credit union debit (not the card, a direct debit by a utility, for example). I write maybe a dozen checks per year, now.
I still use checks for specific things. For example, the local quilt shop requests cash or checks because they hit by large fees for credit card use. To incent folks to use cash or check, they give you a raffle entry with each purchase using those from which they draw a name monthly for a $25 gift certificate to their store. It’s more cost effective for them to do that than pay the credit card fees. I want them to stay in business, so I write a check when I go there.
I also have POA on DS’s bank accounts, and from time to time, he needs me to move money from the credit union to his bank account. Although I can do that electronically, the bank takes 3 business days to credit his account so it is actually faster for me to write a check and use the mobile deposit on my phone to get the money in the account the next day. I really, really want him to get rid of that bank and make the credit union his primary financial institution, but for whatever reason, he likes it as it is.
I find that checks do still have their place, and like credit cards, are just another tool in the financial toolbox.
