Same here but unfortunately not everyone accepts it. Amazon sure didn't and doesn't because eBay a competitor owned Pay Pal at one time.
As a business the only thing I don't like is it takes about 3 days for the money to be deposited in my checking account. My guess is someone's making interest money on that three day float.
I do like my debit card. And it's counterintuitive but I'm less likely to make mistakes in my register with a debit card vs. a check.
